Giants Select Gregory Santos
2:07pm: The Giants announced that Santos has indeed had his contract selected from Sacramento. Oliva was transferred to the 60-day IL to open a spot on the 40-man roster. He’s now out until mid-June at the earliest. San Francisco optioned righty Blade Tidwell to Triple-A to clear a spot on the active roster. Tidwell would’ve been unavailable for several days after tossing 47 pitches in long relief yesterday.
9:21am: The Giants will select the contract of right-handed reliever Gregory Santos from Triple-A Sacramento today, reports Francys Romero of BeisbolFR.com. San Francisco has a full 40-man roster and will need to make a corresponding transaction.
Santos won’t turn 27 until August but already has experience in parts of five major league seasons — including two seasons with the Giants. He originally signed with the Red Sox as a teenager out of his native Dominican Republic but wound up going to the Giants organization alongside righty Shaun Anderson in the 2017 trade that sent utilityman Eduardo Nunez to Boston. Santos made his big league debut with the Giants in 2021 and briefly appeared again in 2022, though he totaled only 5 2/3 innings in orange and black before being designated for assignment and flipped to the White Sox in a cash swap.
Santos had a breakout showing in the South Side bullpen, tossing 66 1/3 frames with a 3.39 ERA, five saves, six holds, a 22.8% strikeout rate, a 5.9% walk rate and a hefty 52.5% grounder rate. Those results, coupled with a sinker that averaged 98.9 mph and a sharp slider averaging 91.3 mph, made Santos look like a potential long-term piece in the bullpen for the White Sox … or for the Mariners, who pounced on that breakout and traded outfielder Zach DeLoach, righty Prelander Berroa and a Competitive Balance Round B pick to the Sox to acquire Santos in February of 2024.
Unfortunately for both the Mariners and Santos, injuries ruined his time with the Seattle organization. Santos suffered a lat strain during spring training just six weeks after the trade and was on the injured list into mid-July. He returned to throw 5 1/3 innings before a biceps injury put him back on the shelf for another eight weeks. Santos did make it back to close out the 2024 season with a pair of scoreless frames, at least giving some hope that he could be on track for a healthier, productive season in 2025.
That didn’t prove to be the case.
Santos opened the 2025 season with diminished velocity and yielded four runs in seven innings (5.14 ERA). He walked eight batters and didn’t strike anyone out. In late April, he underwent surgery to repair some cartilage in his right knee. That procedure effectively ended his season. Santos made it back to a minor league mound in mid-September but issued nine walks against five strikeouts in five rehab innings. He didn’t return to the majors. The Mariners non-tendered him in November.
Now back in the organization for which he made his major league debut, Santos has posted nice results in Triple-A. His sinker and slider are both down a bit more than a mile per hour from their peak, but he’s tossed 11 innings and held opponents to three runs (2.45 ERA) on nine hits and three walks. He’s only fanned six of his 44 opponents (13.6%) and has just a 7% swinging-strike rate, which are both cause for some concern, but he does have three strikeouts in his past 2 2/3 frames (12 batters faced). Given all the recent injuries, some early rust would only be natural.
Time will tell whether this is a a quick cup of coffee or an opportunity to grab a lasting job in the relief corps. Santos has a minor league option remaining, so now that he’s being added to the 40-man, he can be sent down again without needing to pass through waivers. If he can get back to his pre-injury form, he still has at least two seasons of club control remaining beyond the current season.
The Giants don’t have any surefire 60-day IL candidates to open a 40-man spot. Relievers Sam Hentges and Joel Peguero have spent the whole season on the IL but are both on minor league rehab assignments; Peguero is approaching the end of his rehab window. Outfielder Jared Oliva is a candidate after suffering a hamate fracture earlier this month, but while some hitters take eight or more weeks to return from that injury, there are plenty of cases of players returning after only four to five weeks.
Giants Place Daniel Susac On IL, Select Eric Haase
The Giants announced that catcher Daniel Susac has been placed on the 10-day injured list, retroactive to April 20th, due to right elbow neuritis. He’ll miss about two to three weeks, per Alex Pavlovic of NBC Sports Bay Area. Catcher Eric Haase has been selected to take his place on the active roster. To open a 40-man spot for Haase, right-hander José Buttó has been transferred to the 60-day injured list.
Susac was picked up in the Rule 5 draft, via an intermediary. The Twins took him from the Athletics and then flipped him to the Giants for minor leaguer Miguel Caraballo. The Giants had Patrick Bailey lined up as their catcher but Susac and Haase battled for the backup job.
In the end, Susac won the job and has been on a tear. He has a .478/.500/.652 line through his first 24 big league plate appearances. He wasn’t going to hit like that forever, especially with a .550 batting average on balls in play, but the Giants really needed that. Most of the rest of the lineup has been struggling, including Bailey. He is considered by many to be the best defensive catcher in the game but has never been much of a threat from the batter’s box. He has a .226/.283/.331 line in his career and is at .151/.211/.151 this year.
Susac’s strong showing and the general underperformance of the lineup, including Bailey, were seemingly leading to more playing time for Susac. That will be on pause for the next few weeks. Though Susac was due for some regression, it’s still not ideal for him to hit the IL when the club is struggling to score runs.
Haase will jump onto the roster and see if he can make up some of the slack. When Susac won the Opening Day job, Haase was granted his release but then quickly re-signed on a new minor league deal. He has appeared in nine Triple-A games this year with a .250/.300/.472 line.
His best attribute is his power. He had a 22-homer season with the Tigers back in 2021 and has 48 home runs in 1,224 career plate appearances. However, his offense is otherwise poor. His 30.7% career strikeout rate is quite high and he’s been above 40% since the start of 2024. His 6.2% career walk rate is also subpar. Despite the long balls, his career .228/.278/.396 line translates to an 85 wRC+, indicating he’s been 15% worse than the league average hitter.
That’s not necessarily disastrous for a catcher since backstops are usually about 10% below the rest of the league. For a backup catcher, the threshold of respectability is even lower. Unfortunately, Haase isn’t considered a strong defender. He has a minus-12 grade from Defensive Runs Saved in his career behind the plate. Statcast has considered him around par in terms of throwing but below average with blocking and framing.
Haase is out of options and could get squeezed back off the roster when Susac comes back. For now, he’ll try to support Bailey as the Giants try to find some momentum. They’re currently 9-13, with the Mets the only club with fewer runs scored so far. The Giants are hosting the 16-6 Dodgers for a three-game set beginning tonight.

José Buttó Undergoes Procedure For Blood Clot
TODAY: Butto underwent his surgery yesterday, the Giants announced (hat tip to Susan Slusser). The right-hander’s recovery timeline has now been increased to 5-6 months, meaning that Butto’s 2026 season is almost certainly over.
APRIL 4: The Giants announced today that Butto’s recovery timeline is 2-4 months.
APRIL 3: Giants reliever José Buttó has a blood clot in his throwing arm, the team told reporters (via Alex Pavlovic of NBC Sports Bay Area). He’s undergoing a procedure this evening to remove it.
Buttó landed on the 15-day injured list yesterday. The team initially announced that only as arm fatigue. The clot provides a little more clarity, but there’s no return timeline. Susan Slusser of The San Francisco Chronicle relays that it appears Buttó had pitched through the issue for a while before the clot was diagnosed earlier today.
Blood clotting can be associated with thoracic outlet syndrome. That was the case for Phillies ace Zack Wheeler, for example. The Giants have not said anything about whether that’s a fear for Buttó. However, skipper Tony Vitello told Slusser there are a few possible procedures that the right-hander might undergo.
San Francisco acquired Buttó from the Mets as one of three players in the Tyler Rogers deal last summer. Blade Tidwell, another part of the Rogers return, was coincidentally recalled to take his place in the bullpen yesterday. Buttó turned in a 4.50 ERA across 20 innings down the stretch. He surrendered five runs on six hits and four walks over two innings to begin the 2026 season.
NL West Notes: Susac, Bailey, Freeland, Dollander, Ryan
Daniel Susac went 2-for-5 in the Giants‘ 10-5 win over the Nationals yesterday, as the catcher is now hitting an absurd .524/.545/.714 over the first 22 plate appearances of his Major League career. Susac was a Rule 5 Draft pick initially from the Athletics organization before he was taken by the Twins and then immediately dealt to the Giants.
A big Spring Training performance clinched Susac’s roster spot and a role as Patrick Bailey‘s backup, yet Susac’s dream start is earning him more playing time, with starts in three of San Francisco’s last five games. On Thursday, Giants manager Tony Vitello told the San Francisco Chronicle’s Susan Slusser and other reporters that the team intends on “involving [Susac] as much as possible, see if we get into an every other day situation, or whatever it might be.”
Bailey has never shown much at the plate over his four MLB seasons, but he is off to a particularly ugly start by hitting only .128/.180/.128 in 50 PA. While Bailey’s elite defense has been reason enough to earn him starting catcher duties in the past, the Giants’ offense has struggled so much (Friday notwithstanding) that the club has nothing to lose by riding the hot hand in Susac.

- Kyle Freeland‘s MRI on his inflamed left shoulder didn’t reveal any structural damage, Rockies manager Warren Schaeffer told the Denver Post’s Patrick Saunders and other reporters. Freeland was retroactively played on the 15-day injured list on April 13, and the good diagnosis means that the veteran southpaw likely won’t miss too much time. The injury interrupted Freeland’s strong start to the season, as he had a 2.30 ERA over his first three outings.
- Chase Dollander is another Rockies pitcher getting good early results, as the former third overall pick has a 3.32 ERA, 28.7% strikeout rate, and 7.5% walk rate over 19 innings. Dollander has yet to start any of his five appearances, however, and Schaeffer told Saunders and company that Dollander will continue pitching behind an opener for the time being. The manager’s logic is simple: Dollander is “having a lot of success” as a bulk pitcher. “He’s settled into a routine, and routines are very different from being in the bullpen and starting. Obviously, we want him to be a starter, long-term. But right now we don’t want to mess with the routine,” Schaeffer said.
- The Dodgers‘ Triple-A affiliate in Oklahoma City placed River Ryan on the seven-day injured list yesterday, and Jack Harris of the California Post indicated that the placement is likely due to a hamstring injury. Ryan posted a 1.33 ERA over his first 20 1/3 MLB innings in 2024, but a Tommy John surgery in August of that year sidelined the right-hander for the entirety of the 2025 campaign. Returning to action with Oklahoma City this year, Ryan’s excellent peripherals and a .450 BABIP over seven innings of work indicate that he has pitched much better than his 5.14 ERA would imply. The IL stint will delay his eventual return to Los Angeles in what will probably be a bullpen role, as there isn’t room for Ryan even in a six-man Dodgers rotation if everyone is healthy.
The Giants’ Punchless Early-Season Offense
The Giants are among the three teams off to a 6-11 start, tying them with the rebuilding Rockies and White Sox for the worst record in MLB through three weeks. It's much too early to write them off, but it has unquestionably been a rough start. They're riding a three-game losing skid into tonight's game in Cincinnati and have been outscored by 22 runs. Only the White Sox and an injury-riddled Blue Jays team have a worse run differential.
San Francisco has been mostly healthy. Their only rotation injury was losing projected sixth starter Hayden Birdsong to elbow surgery late in camp. Their position players had been fully healthy until this afternoon's injured list placements for center fielder Harrison Bader and pinch-runner/fifth outfielder Jared Oliva.
They do have a number of injured relievers, though most of those were known coming into the season. Randy Rodríguez went down to Tommy John surgery last September. They signed Sam Hentges and Jason Foley knowing neither player would be ready for Opening Day. They've lost a couple middle relievers (Reiver Sanmartin, Joel Peguero and José Buttó) since Spring Training, but that's about it. Their early-season struggles have been much more attributable to underperformance than injury.
That's especially true since the bullpen hasn't been the biggest culprit to the slow start. It hasn't been good, but they're 18th in ERA (4.39) and have blown two leads on the season. The pitching in general has been average, about what one would expect given the personnel. The offense has been the much bigger disappointment.

Giants Place Harrison Bader, Jared Oliva On Injured List
The Giants have placed outfielders Harrison Bader and Jared Oliva on the 10-day injured list, per a club announcement. The former is dealing with a hamstring strain, while the latter was diagnosed with a hamate fracture, likely pointing to a somewhat notable absence. Bader’s IL placement is retroactive to April 12. Fellow outfielders Will Brennan and Drew Gilbert have been recalled from Triple-A in their place.
Bader, 31, has gotten out to a dismal start in his new environs. Signed to a two-year, $20.5MM contract in free agency, he’s started his Giants tenure with a .115/.145/.192 batting line and a glaring 30.9% strikeout rate in 55 turns at the plate. The longtime defensive standout had one of his best seasons at the plate in 2025, slashing a combined .277/.347/.449 with a career-best 17 homers in 501 plate appearances between Minnesota and Philadelphia.
It’s obviously a bit early to sound the alarm, but it’s a brutal stretch of 15 games for Bader, who hasn’t experienced strikeout troubles of this magnitude since 2018 with the Cardinals. Bader’s chase rate on balls off the plate is up six percentage points this year, while his contact rate on balls within the strike zone is down more than three percentage points. He’s been extremely aggressive early in his plate appearances and has too often found himself behind in the count as a result.
The Giants haven’t provided a firm timetable, but Bader will be down for the next week-plus at the very least. If it’s a lengthy enough stay on the IL, he could require a minor league rehab stint. For the time being, San Francisco can either slide Jung Hoo Lee back to center field or give some of that workload to Gilbert and Brennan. Lee hasn’t graded out well in his time as a center fielder in the majors — which was surely part of the Giants’ motivation in signing Bader, who perennially ranks as one of the game’s top outfield defenders. Gilbert has played all three outfield slots in Triple-A this season, spending the bulk of his time in center. Brennan has played the corners only in 2026 but has nearly 1800 professional innings in center.
As for the 30-year-old Oliva, this is his first big league action since 2021 with the Pirates. He’s appeared in seven games but been primarily a defensive replacement and pinch-runner. He’s had seven at-bats and tallied one single in that time.
Oliva impressed the Giants with plus speed and outfield range in camp this spring. In 20 games/46 plate appearances, he swiped a ludicrous 14 bags while also turning in a robust .375/.444/.550 batting line. That was more than enough for Oliva to earn a spot on the roster, even pushing out-of-options former top prospect Luis Matos out the door in the process.
Hamate fractures typically require surgery and come with a recovery period between four and eight weeks. Every instance is different, of course, but that general framework is at least worth noting. It’s doubtful Oliva will be back any earlier than mid-May, and his absence could push into early-to-mid June. Assuming Bader returns to the fold before Oliva, Gilbert stands as a natural option to fill the backup outfield role that Oliva has held throughout the season.
NL West Notes: Tatis, Arraez, Hentges, Snell, Edman
Fernando Tatis Jr. was 3-for-4 with a walk and an RBI in yesterday’s 9-5 Padres win over the Rockies, but the most notable aspect of Tatis’ game was his role as San Diego’s starting second baseman. It was just Tatis’ second career big league game at second base and his first start at the position, and the move came about since shortstop Xander Bogaerts had a day off. “We felt like Tatis was the best option at second base, and the most fun and exciting option at second base,” manager Craig Stammen told The Athletic’s Dennis Lin and other reporters, as the Padres look for ways to juggle their lineup, find at-bats for everyone, and keep their players fresh.
Needless to say, Tatis isn’t leaving his regular right field spot any time soon, but getting the odd game in at the keystone can add to his already high defensive value. Stammen also suggested that the position change might get Tatis rolling after a slow start at the plate, and Tatis’ three-hit night indicates that the tactic may have worked.

- X-rays were negative on Luis Arraez‘s right wrist after the Giants second baseman was removed from yesterday’s game. An unusual play at second base saw Dylan Beavers accidentally kick Arraez in the hand while trying to avoid a tag in the bottom of the fourth inning, and Arraez was removed before the bottom of the fifth. Arraez is day-to-day for now, and since the Giants don’t play on Monday, it seems likely that he’ll be held out of today’s lineup to get two full days of recuperation. After signing a one-year, $12MM free agent deal with San Francisco, Arraez is off to a nice start with his new team, hitting .304/.339/.393 over his first 63 plate appearances.
- Sam Hentges also joined the Giants on a one-year, $1.4MM deal this offseason, and the reliever looks to finally be nearing his first game action of any kind since August 2024, as the A-level San Jose Giants announced that Hentges is joining the team on a rehab assignment. Hentges posted a 2.93 ERA, 27.7% strikeout rate, and 7.5% walk rate over 138 innings out of the Guardians’ pen in 2022-24, but his career was then put on hold by a shoulder surgery in September 2024, and then an arthroscopic right knee surgery last September. The left-hander’s rehab assignment figures to be pretty lengthy given how long Hentges has been sidelined, but he could be an intriguing x-factor in San Francisco’s bullpen when healthy.
- Blake Snell threw a 15-pitch simulated inning yesterday, facing live batters for the first time since Game 7 of the World Series. Snell began the season on the Dodgers‘ 15-day injured list due to shoulder fatigue, and he said a month ago following his first Spring Training bullpen session that he was aiming to make his season debut before the end of April. That timeline might be delayed slightly, as manager Dave Roberts told MLB.com’s Courtney Hollmon and other reporters that the team wants to see Snell built up in throwing sessions to the equivalent of four innings before Snell goes on a rehab assignment.
- Tommy Edman was one of the batters at the plate during Snell’s sim inning, which also marked the first time Edman had faced live pitching since he underwent ankle surgery last November. Edman began the season on the 10-day injured list but Roberts told Hollmon and company that the Dodgers aren’t expecting Edman back until closer to the end of May since he is “not at full speed” yet in terms of running. The timing means that Edman could be shifted to the 60-day IL at some point if Los Angeles needs a 40-man roster spot, though that decision won’t be made until Edman is deeper into the recovery process.
Blue Jays Acquire Tyler Fitzgerald
The Blue Jays and Giants have each announced that utilityman Tyler Fitzgerald has been traded to the Jays in exchange for cash considerations. Fitzgerald has been optioned to the Jays’ Triple-A affiliate. Toronto has an open spot on its 40-man roster, so no corresponding move was necessary.
San Francisco designated Fitzgerald for assignment earlier this week, and today’s deal officially ends a tenure that began when the Giants made Fitzgerald a fourth-round pick in the 2019 draft. He made his MLB debut in the form of 10 games in 2023, and seemingly had a breakout in 2024 when he hit .280/.334/.497 over 341 plate appearances. Fitzgerald also hit 15 homers and stole 17 bases in 21 attempts, and he finished the season with a 132 wRC+ and 3.0 fWAR.
Perhaps the key statistic, however, was Fitzgerald’s .380 BABIP. Reality may have sunk in last season, as Fitzgerald’s BABIP fell to a more standard .299, and his offensive production cratered. Fitzgerald hit .217/.278/.327 over 243 PA in 2025, translating to a 72 wRC+. The Giants used Fitzgerald as their regular starting second baseman in the early part of the season, but he was optioned to Triple-A in June, and played in only 15 MLB games after June 29 after being repeatedly called up and sent back down to the minors.
A left rib fracture sent Fitzgerald to the 10-day injured list for a little over two weeks at the start of May, which ended up being the demarcation line of his season. Fitzgerald was hitting a respectable .284/.341/.432 in 90 PA before the IL trip, so he was never the same after his rib issue.
The Giants’ offseason signing of Luis Arraez to play second base assured that Fitzgerald would be a bench option at best in San Francisco this season. The team started him at Triple-A to begin the season, and then decided to move on entirely via the DFA route.
The big majority of Fitzgerald’s MLB playing time has come at shortstop, but he has seen time at every position on the diamond except catcher. This versatility makes him a useful depth option for a Blue Jays club that doesn’t really have a true backup infielder on their current 26-man roster. Toronto has a set everyday infield of Vladimir Guerrero Jr., Ernie Clement, Andres Gimenez, and Kazuma Okamoto. Davis Schneider and Addison Barger can respectively play second or third base when they’re not in the outfield, and Clement can be a backup shortstop if Schneider is at second base.
After the out-of-options Leo Jimenez was traded to the Marlins, Rafael Lantigua and prospect Josh Kasevich (both at Triple-A Buffalo) became Toronto’s top utility infield options, though neither player is on the 40-man roster. Fitzgerald’s addition gives the Jays a player they can move back and forth between Triple-A and the bigs, as Fitzgerald has one more minor league option year remaining.
Giants Re-Sign Eric Haase To Minor League Deal
The Giants have apparently re-signed catcher Eric Haase to a minor league contract. The Warner Sports Management client is in the lineup tonight for Triple-A Sacramento. Haase had been released from his previous minor league deal at the end of Spring Training.
He was competing with Rule 5 pick Daniel Susac and prospect Jesús Rodríguez for the backup job behind Patrick Bailey. The 33-year-old Haase hit .286 with a couple home runs while striking out 14 times in 32 plate appearances this spring. San Francisco stuck with Susac in the backup role. They optioned Rodríguez while granting Haase his release.
After a few days on the open market, Haase returns to the club. He’ll work alongside Rodríguez and Logan Porter as part of the Triple-A catching group. Haase has easily the most MLB experience of any catcher in the organization aside from Bailey. He has just over four years of service time and has taken more than 1200 plate appearances in a little under 400 games.
Haase is a lifetime .228/.278/.396 hitter at the big league level. He has plus power from the right side that comes with a lot of swing and miss. Haase has always been a bat-first option who probably profiles best in the third catcher role he’ll play now that he’s back with San Francisco.
Padres Notes: Arraez, Adam, Song
Luis Arraez made his return to San Diego yesterday for the first time since signing with the division rival Giants in free agency. Speaking to reporters (including Jeff Sanders of the San Diego Union-Tribune), Arraez revealed that he “talked a lot” with the Padres during free agency before ultimately signing in San Francisco.
It’s a decision that Arraez chalks up to his desire to play second base, which wasn’t on the table in San Diego due to the presence of Jake Cronenworth. The Giants afforded him that opportunity, and Sanders notes that the $12MM salary he received from his new club was more than the Padres could offer. Considering that Michael King is San Diego’s only offseason addition making even $3MM in 2026, that certainly seems like a fair assessment.
Even if the team’s financial situation made a reunion all but impossible, Arraez’s strong desire to play second base this year does shed some light on his free agency. The soon-to-be 29-year-old posted the worst season of his career last year, hitting just .292 with a 104 wRC+. It seemed as though that left Arraez to sit through a very quiet offseason where his name rarely appeared in the rumor mill, if ever. Perhaps, however, Arraez’s desire to play second limited his market more than it otherwise would have. Teams like the Mariners, Yankees, Red Sox, Orioles, Diamondbacks, and the Padres themselves were all looking for help at first base this offseason, while teams on the hunt for second base help were far more limited. The Red Sox, Giants, and A’s were three of the only clubs looking to add at the keystone this winter, and Boston was known to be prioritizing defense.
That surely left Arraez with a very limited market in terms of teams willing to hand him the second base job, but that list could expand if he turns in a strong season this year. Of course, a tough season or even one where he doesn’t prove himself capable of handling the keystone could leave him looking at an even softer market next year. As Arraez himself pointed out to Sanders, his contract with San Francisco is for just one year.
“I don’t know what (will happen) later,” Arraez said of his future after the 2026 campaign (as relayed by Sanders).
In other Padres news, Sanders writes that right-hander Jason Adam threw 1 1/3 scoreless frames on a rehab assignment over the weekend and is making good progress as he looks to return from quadriceps surgery. The righty is poised to throw in a simulated game today before making back-to-back rehab appearances on Friday and Saturday. If those outings all go well, that could set him up for a return not long after his minimum IL stint date of April 8. When he does return, Adam will be a huge boon to the Padres’ bullpen. The veteran righty has been one of the best relief arms in baseball over the past few years, with a 2.07 ERA and 3.20 FIP since the start of the 2022 campaign. He’ll join a crowded high leverage mix alongside Mason Miller, Adrian Morejon, and Jeremiah Estrada once he’s back in action.
Speaking of rehab assignments, infielder Sung Mun Song is rehabbing after opening the year on the shelf due to oblique tightness. MLB.com notes that he began a rehab assignment last week, and he’s appeared in three games since. That includes appearances at second base and shortstop, suggesting that he might not be too far from being healthy enough to return. The 29-year-old is waiting to make his big league debut after signing out of the KBO with the Padres on a four-year, $15MM pact over the offseason. He figures to factor heavily into the club’s bench mix once healthy, seeing time all over the infield and perhaps even in the outfield corners this year.
