Nationals Place Andrew Chafin On 15-Day Injured List

By | at

The Nationals announced that left-hander Andrew Chafin has been placed on the 15-day injured list due to a right hamstring strain.  Chafin’s placement is retroactive to June 11.  Right-hander Ryan Loutos (who was claimed off waivers from the Dodgers earlier this week) was called up from Triple-A in the corresponding roster move.

Signed to a one-year, $1MM Major League deal at the start of May, Chafin has a 3.18 ERA over 11 1/3 relief innings for Washington.  The secondary metrics include a 25.9% strikeout rate that exactly matches Chafin’s career average, as well as a 57.1% groundball rate that harkens back to Chafin’s early-career model as more of a groundball specialist.  Chafin has yet to allow a home run this season, which partially explains why he has kept his ERA in check despite a huge .414 BABIP and an uncharacteristically huge 20.4% walk rate (almost double his career 10.3BB%).

Chafin has traditionally kept pretty even numbers against both left-handed and right-handed batters, though his splits are rather pronounced this year — right-handed hitters have an .871 OPS over 26 plate appearances and lefty batters have only a .607 OPS in 28 PA.  Chafin, Jose A. Ferrer, and Colin Poche (who is now in the Mets organization) are the only left-handers who have seen action in Washington’s bullpen this season, and Ferrer is now the last southpaw standing with Chafin sidelined.

The severity of the hamstring strain isn’t yet known, so for now there isn’t any reason to expect Chafin to be out of action for much more than the 15-day minimum.  The 30-39 Nationals will need to really heat up in order to avoid being sellers at the trade deadline, and a veteran rental pitcher like Chafin would seem like a prime candidate to be moved if healthy.

Mets Notes: Siri, Winker, Senga, Montas, Raley

By | at

Mets president of baseball operations David Stearns and manager Carlos Mendoza each provided several injury updates when speaking with reporters (including Newsday’s Laura Albanese, The Athletic’s Tim Britton, and the New York Post’s Mike Puma) on Friday.  The most unwelcome bit of news concerned Jose Siri, whose recovery from a left tibia fracture will be delayed since tests showed the tibia hadn’t healed as well as expected over two months since the initial injury.

Siri last played on April 12, when he fouled a ball off his left leg during his first plate appearance in the Mets’ 3-1 loss to the Athletics.  The initial recovery timeline was set at 8-10 weeks, though in the wake of this latest setback, Siri will now be shut down from baseball activities for a few more weeks until he undergoes a fresh round of imaging tests.

Even if those tests reveal better results, Siri will need to ramp his rehab back up and play in multiple minor league games, so it may be optimistic to expect Siri back on New York’s big league roster before July is over.  It’s a frustrating setback for Siri, who seemed to be making progress by taking part in live batting practice sessions and doing some running drills in recent weeks.  Instead, it now looks like he’ll miss over half of the season on the injured list, leaving the Mets without a key member of their outfield.

Acquired from the Rays in a trade last November, Siri was meant to add some power and (most pressingly) defensive stability to the Amazins’ center field mix.  His absence has made Tyrone Taylor more or less the everyday center fielder, and while Taylor has held his own with the glove, he is hitting only .234/.300/.332 over 205 plate appearances.  The left-handed hitting Jeff McNeil has been spelling Taylor in center field when McNeil isn’t at second base, and Jose Azocar, Brandon Nimmo, and Luisangel Acuna have made a few cameos in center when the situation has warranted.

It was already expected that the Mets would be looking for some outfield help at the trade deadline, and the possibility that Siri might not even be back by July 31 only underlines the outfield as a target area.  Perhaps if the Mets are okay with the Taylor/McNeil platoon in center field, the club might just look to add a bat in general to help out in the infield or in the DH position.  Designated hitter Jesse Winker is recovering from a Grade 2 oblique strain that has kept him out since early May, and Stearns said that Winker will still need multiple weeks before a minor league rehab assignment is considered.

Kodai Senga’s hamstring strain created a big hole in New York’s rotation this week, though Mendoza said tests revealed that Senga had only a Grade 1 strain, or the least severe variety.  The current plan is for Senga to be shut down for two weeks and then the club will explore plans for a throwing progression and a minor league rehab assignment.  Given the timing, it seems possible Senga might be able to pitch again before the All-Star break, but in all likelihood the Mets will play it safe with their ace and hold him out through the break to give him a few more days of rest.

The Mets’ rotation has been plagued by injuries ever since Spring Training, yet the staff has greatly exceeded expectations by still leading all of baseball with a 2.78 rotation ERA.  Senga’s 1.47 ERA over 73 2/3 innings has been a big part of that success, as the right-hander has returned in top form after missing virtually all of the 2024 season.

Paul Blackburn will move from a long relief/swingman role into the rotation to fill in for Senga, while Britton suggests that Frankie Montas might move into the bullpen in Blackburn’s role (rather than into a starting job) when Montas is activated from the 60-day injured list.  After missing the entire season due to a lat strain, Montas has made five minor league rehab starts, and June 22 will mark the end of the allotted 30 days for Montas’ rehab assignment.

While in-game results are usually less important than fitness and mechanics during these rehab outings, Montas’ 13.17 ERA over 13 2/3 innings with high-A Brooklyn and Triple-A Syracuse is hard to ignore, as the veteran righty is clearly still not on track.  Stearns said that Montas will make one more start in the minors, and that Montas “is still searching a little bit” after such a long layoff.

“Physically, we are trending in the right direction and now it’s just getting him back into the rhythm,” Stearns said.  “This is very similar to a Spring Training ramp up where you try not to focus on results too much early and then as you get a little bit later in the ramp up you want to start seeing outs.  That is where Frankie is right now.”

In even longer-term injury news, Brooks Raley could be starting a rehab assignment within the next week.  Raley underwent a Tommy John surgery in May 2024, and with the knowledge that he’d miss most of the 2025 season, the Mets inked the veteran reliever to a one-year free agent deal that guarantees Raley $1.85MM ($1.5MM in 2025 salary, and a $300K buyout on a $4.75MM club option for 2026).

Several other performance bonuses are available both this season and next depending on how many appearances Raley can make, though the first order of business is simply getting the southpaw back in action.  Britton notes that Raley will likely need the full 30-day rehab window in order to get back into game shape, so if all goes well, Raley could be an option for the Mets’ bullpen before the end of July.

Should The Braves Consider Offers On Chris Sale?

By | at

The Braves have continued to underperform as the season nears its three-month mark. They clawed back from their 0-7 start to get above .500 in mid-May -- right as they were about to activate Ronald Acuña Jr. and Spencer Strider from the injured list. Optimism was high. Then came a stretch of 14 losses in 17 contests that dropped them to a season-high 10 games below .500 over the weekend. They're coming off a solid series win in Milwaukee, but they face long odds to climb back into a tough NL playoff race. The division is all but gone, and they're nine games back with six teams to jump in the Wild Card picture.

Atlanta's front office isn't going to sell six weeks in advance of the trade deadline. They've invested a lot and this core's prior successes have earned them as much runway as possible to get hot. Jon Heyman of The New York Post wrote last night that the Braves still view themselves as buyers, highlighting shortstop and the outfield as potential targets.

Still, they're running low on time and coming off their worst stretch of the season. The back half of the lineup, late-inning relief mix, and starting pitching depth are all issues. They'll need a significant turnaround in the next 4-6 weeks to avoid selling some short-term pieces. Marcell Ozuna would be an obvious candidate as a rental bat who is raking for a third consecutive season. They could try to offload impending free agent reliever Raisel Iglesias, who has put himself on shaky ground by struggling with the longball. The tougher question is whether the front office should move any key players who are controllable beyond this year -- with Chris Sale leading the way as the team's top option.

White Sox, Brewers Swap Aaron Civale, Andrew Vaughn

By and | at

The White Sox acquired right-hander Aaron Civale and cash considerations from Milwaukee for first baseman Andrew Vaughn. The Brewers optioned Vaughn to Triple-A Nashville, while Civale will step directly into Chicago’s rotation. The Brewers are reportedly sending cash to offset the difference in remaining salary between Civale’s $8MM sum and Vaughn’s $5.85MM figure.

It’s a quick turnaround after Civale requested a trade away from Milwaukee on Thursday. Civale’s trade request came on the heels of the club’s decision earlier this week to bump him from the rotation in order to call up top pitching prospect Jacob Misiorowski. Civale, a free agent after the 2025 campaign who struggled a bit last year but has pitched to a 3.32 ERA and 3.92 FIP in four starts since returning from the injured list last month, evidently wants to hold onto a rotation job to set himself up for success in free agency this winter as much as possible.

The 30-year-old’s wish was promptly granted, as he’s now headed for the White Sox. The South Siders have no real hope of competing for a playoff spot this year, but with a patchwork rotation that features multiple Rule 5 draftees it’s not hard to see Civale as a potentially substantial upgrade for their starting rotation. While a team headed for their second-consecutive 100-loss campaign acquiring a rental starting pitcher in the middle of the season is a rare occurrence, one can see the logic from Chicago’s perspective given that they’ll have the opportunity to flip Civale to a club with postseason aspirations closer to the trade deadline.

The logic is particularly sound for the White Sox given the player they’re giving up in return. Vaughn was the third-overall pick in the 2019 draft and a longtime top 100 prospect, but his major league career has been a disappointment so far. He entered the 2025 season with a career .253/.310/.415 (102 wRC+) slash line at the major league level and has had just one season where he had hit at a clip substantially better than league average. Things took a more pronounced nosedive this year, as he’s slashed just .189/.218/.314 (44 wRC+) across 48 games for the White Sox in 2025. It’s the lowest on-base percentage of any player with at least 120 plate appearances in the majors this year, and his -1.3 fWAR this season is dead last among all hitters who have stepped up to the plate in the majors this season. The Sox optioned him to Triple-A Charlotte a few weeks ago and he has hit .211/.328/.351 in 15 games for the Knights since then.

That’s not a player the White Sox could expect to get a substantial prospect return for this summer, and while Vaughn has one year of control remaining after this one he currently has the look of a clear non-tender candidate. That surely made the opportunity to roll the dice on flipping a veteran starting pitcher a very attractive option for Chicago.

With all that being said, it’s not as though the deal doesn’t make sense for the Brewers. Civale no longer fit in an increasingly deep Brewers rotation mix, and his roster spot is likely better used on other arms more suited for bullpen duty than a veteran starter with zero career relief appearances. What’s more, Vaughn’s underlying numbers paint the picture of a player whose actual performance isn’t all that different from his previous seasons as a league average hitter. While he’s walking at a career-low 3.6% clip, he was never an especially patient hitter. His 22.3% strikeout rate is only a tick higher than last year, and his 13.3% barrel rate this season is actually the best of his career and four points better than last season. Vaughn’s ghastly .217 BABIP should improve with time, and with incumbent first baseman Rhys Hoskins likely ticketed for free agency this winter getting Vaughn on board as a much cheaper possible replacement makes sense.

In the shorter term, Vaughn will serve as minor league depth. The Brewers reportedly view him as a full-time first baseman/DH even though he has experience in the outfield.

Jon Heyman of The New York Post first reported that Milwaukee was trading Civale to the White Sox. Jesse Rogers of ESPN reported that Vaughn was headed back to the Brewers. Adam McCalvy of MLB.com reported the cash exchange.

Astros To Select Luis Guillorme

By | at

The Astros will select infielder Luis Guillorme onto the MLB roster tomorrow, reports Chandler Rome of The Athletic. Houston has an open 40-man roster spot after designating Forrest Whitley for assignment and trading him to Tampa Bay. They’ll need to make an active roster move.

Guillorme has spent the entire season at Triple-A Sugar Land on a minor league contract. The lefty-hitting infielder owns a .245/.376/.310 line across 242 plate appearances. He has walked in 17% of his trips against a 19% strikeout rate, but he only has a pair of home runs. That’s in line with Guillorme’s track record. He’s a patient hitter with good contact skills and bottom-of-the-scale power.

A career .251/.336/.322 hitter over parts of seven MLB seasons, Guillorme is valued most highly for his defense. He has ample experience at each of the three infield spots to the left of first base. He hasn’t played much shortstop this year in the minors, though he won’t be needed there in the majors either because of Jeremy Peña. Guillorme can push Brendan Rodgers for playing time at the keystone while offering short-term insurance as Isaac Paredes navigates an injury.

Paredes left last night’s game with left hamstring discomfort. He didn’t play tonight; Mauricio Dubón drew into the lineup at the hot corner. Manager Joe Espada told the Houston beat that Paredes has been diagnosed with a strain but it’s seemingly mild, as he added that the team believes the infielder will avoid the injured list (relayed by Brian McTaggart of MLB.com).

The corresponding active roster move may be an IL stint for rookie outfielder Jacob Melton. The 24-year-old sprained his right ankle during tonight’s game, Espada said. Houston will have Jose Altuve, Jake Meyers and Cam Smith as their starting outfield but may need to use Dubón more often as a fourth outfielder with Melton out.

A.J. Puk Halts Throwing Program With Elbow Discomfort

By | at

Diamondbacks reliever A.J. Puk has paused his throwing program after experiencing renewed elbow soreness, manager Torey Lovullo told reporters on Friday (link via Nick Piecoro of The Arizona Republic). Puk will visit Dr. Neal ElAttrache before deciding on next steps. Lovullo called it “slight discomfort” and noted that the star southpaw initially hoped he could continue throwing through it.

Puk has been out since the middle of April with a flexor strain. The organization has remained hopeful that he’ll be able to rehab the injury without requiring surgery. That’s presumably still the case, but any kind of setback for a forearm/elbow injury is worrisome. That’s especially true considering Puk has a 2018 Tommy John surgery on his medical chart. Even if the follow-up visit goes well, the shutdown will push back his return timeline to some extent.

It’s the latest bad news for a reeling Arizona bullpen. Puk and Justin Martinez were supposed to serve as Lovullo’s 1-2 punch in the late innings. Puk made eight appearances before his IL stay. Martinez got into 17 games and suffered an elbow injury of his own last week. That one immediately proved serious, and the team announced this evening that he’s headed for the second elbow surgery of his career.

Arizona’s bullpen has been a huge weakness. They entered play tonight with a 5.21 earned run average that ranks 27th in MLB. The injuries to Puk and Martinez are the biggest factors, but they’ve also seen former key contributors Ryan Thompson and Kevin Ginkel struggle through rough years. Low-cost acquisitions Shelby Miller and Jalen Beeks have been their most reliable relievers. The D-Backs will need to acquire multiple bullpen arms if they’re in position to add at the deadline.

Mariners Select Zach Pop

By | at

The Mariners announced they’ve selected righty reliever Zach Pop onto the big league roster. Rookie starter Logan Evans was optioned back to Triple-A Tacoma to create an active roster spot. Seattle had two openings on the 40-man roster.

Pop will make his team debut whenever he gets into a game. He joined Seattle in mid-April on a minor league deal. That came after he was released by the Blue Jays. Pop was battling elbow inflammation at the time, but he got back on the mound by the middle of May. He made two rehab appearances in the complex league before reporting to Tacoma. Pop has made 11 appearances and tossed 9 2/3 innings, allowing seven runs (though only three were earned). He has fanned nine against five walks.

The 28-year-old Pop has pitched in parts of four MLB seasons. He threw 48 1/3 frames for the Jays last season, working to a 5.59 ERA with a well below-average 15.8% strikeout percentage. Pop doesn’t have huge swing-and-miss stuff, but he sits around 96 MPH with his sinker and has posted a gaudy 55% ground-ball rate in his career. He’ll add a grounder specialist to Dan Wilson’s middle relief corps for the time being. He’s out of minor league options, though, so the M’s would need to designate him for assignment to take him off the big league roster.

Seattle can operate with an extra reliever for this weekend’s series against the Guardians. Luis Castillo, George Kirby and Emerson Hancock are lined up to start those games. Adam Jude of The Seattle Times writes that Logan Gilbert is expected to return from the injured list during next week’s series against the Red Sox, at which point Seattle will go back to five starters and an eight-man bullpen. Gilbert has been down since late April with a flexor strain. He has made a trio of rehab starts with Tacoma, combining for 9 2/3 innings of three-run ball.

Jose Urena Elects Free Agency

By | at

Veteran righty José Ureña elected free agency, according to the MLB.com transaction log. He evidently went unclaimed on waivers after being designated for assignment by the Dodgers on Tuesday.

Ureña made two appearances after signing with L.A. on June 3. He tossed three innings of one-run ball, recording two strikeouts with one walk. Ureña has now suited up for three MLB teams this season. He has also logged time with the Mets and Blue Jays, managing 18 1/3 innings over a combined nine appearances. Ureña has punched out 10 against five walks while recording a 5.40 earned run average in that time.

The 33-year-old righty will again look for an opportunity to pitch in a swing capacity. While he has bounced around this year, Ureña held a spot on the Texas pitching staff throughout the ’24 season. He posted a 3.80 ERA while getting ground-balls at a 50% clip in 109 innings for the Rangers. Ureña has never had good strikeout and walk numbers, but his sinker averages 96-97 MPH and he’s capable of covering multiple innings.

Justin Martínez To Undergo Tommy John Surgery

By | at

Diamondbacks right-hander Justin Martínez will undergo Tommy John surgery. Arizona manager Torey Lovullo relayed the info today, per John Gambadoro of Arizona Sports 98.7 FM Phoenix. He’ll miss the remainder of this season and a decent chunk of 2026 as well. He is already on the 15-day injured list but will be transferred to the 60-day IL once the club needs to open a roster spot.

The news is devastating but not especially surprising. Earlier this week, Martínez landed on the IL and the Diamondbacks announced his injury as a sprain of his right ulnar collateral ligament. A sprain, by definition, involves some degree of stretching or tearing. Not all UCL sprains lead to surgery but many do.

Now that Martínez will go under the knife, he’ll be out of action for a long time. The surgery usually takes 14 to 18 months of recovery, so he’ll certainly out for the rest of this season. A return in the second half of 2026 is possible but not a guarantee.

That’s a huge blow for the Arizona bullpen. Martínez broke out last year with 72 2/3 innings with a 2.48 earned run average. His 11.7% walk rate was a bit high but he punched out 29.5% of batters faced and got opponents to pound 58.9% of balls in play into the ground.

Coming into 2025, he and A.J. Puk were supposed to be the anchors of the bullpen. The Snakes even gave Martínez a five-year, $18MM extension to cement him as part of the long-term plans. But Martínez has been on and off the IL this year, first due to shoulder inflammation and now this UCL injury. Puk has also been on the IL for almost two months now due to elbow inflammation.

Naturally, missing those two has hampered the bullpen. Arizona relievers have a collective 5.21 ERA this year, which is better than just the Angels, Nationals and Athletics. The club is 34-34 on the year, 4.5 games back of a playoff spot. Puk could be back at some point later in the year but they will have to try to survive without Martínez. If they hang in the race long enough to be buyers, then adding bullpen help at the deadline would make plenty of sense.

For the team, there is one silver lining. The extension they signed with Martínez contained two club options for 2030 and 2031, followed by a conditional club option for 2032. That conditional option would be worth $3MM and would be unlocked if Martínez required elbow surgery or spent a certain number of days on the injured list during the course of the deal. Now that he is going under the knife, that option will be officially available to them.

That’s assuming Martínez can get back on the mound and return to his previous form, which would prompt the Snakes to pick up those club options. Though Tommy John surgeries are quite common, not all pitchers can get 100% effectiveness back afterwards. Martínez is also undergoing the procedure for a second time, which adds to the risk. He first went under the knife as a prospect in 2021.

White Sox Claim Ryan Noda, Designate Joshua Palacios For Assignment

By | at

The White Sox announced that they have claimed first baseman Ryan Noda off waivers from the Red Sox and optioned him to Triple-A Charlotte. Boston had designated him for assignment a few days ago. Outfielder Joshua Palacios has been designated for assignment to open a 40-man spot. Infielder Brooks Baldwin has been recalled to take the active roster spot of Palacios. There was also a swap on the pitching side, with left-hander Tyler Gilbert reinstated from the injured list and righty Owen White optioned as the corresponding move.

Noda, 29, has an extreme profile. He strikes out a lot but also draws plenty of walks and has some pop. He has done that all throughout his minor league career and then showed it at the big league level in 2023 after the A’s grabbed him from the Dodgers in the Rule 5 draft. He got into 128 games and stepped to the plate 495 times. He struck out in 34.3% of those plate appearances but also walked at a massive 15.6% clip and hit 16 home runs. That all added up to a .229/.364/.406 line and 122 wRC+.

Last year, he got out to a rough start and ended up getting optioned to the minors for most of the year. The A’s put him on waivers at the end of the season, with the Angels putting in a claim. He was designated for assignment about a month ago and got flipped to the Red Sox in a cash deal. Both the Angels and the Red Sox kept him on optional assignment.

His minor league numbers have continued along with Noda’s usual style. Dating back to the start of last year, he has 655 Triple-A plate appearances with 29 homers, a 20.2% walk rate and a 30.4% strikeout rate.

The White Sox came into this year with Andrew Vaughn as their primary first baseman. He struggled badly enough to get optioned to the minors a few weeks back. Earlier today, the Sox flipped him to the Brewers for Aaron Civale and cash. Tim Elko has been getting a lot of the playing time at first lately but is hitting .155/.222/.379. If that continues, perhaps the Sox will make a switch.

Palacios, 29, signed a minor league deal and then was added to the roster in April. He has 145 plate appearances so far this year with a .203/.292/.305 line. That now gives him a career .223/.287/.349 batting line and 75 wRC+.

Since he’s out of options, he can’t be easily sent down to the minors. He’ll now be in DFA limbo, which can last for at most a week. The waiver process takes 48 hours, so the Sox could take five days to try to line up a trade. He cleared waivers back in March and hasn’t done much to improve his stock since then, so the level of interest should be low. If he clears waivers, he will have the right to elect free agency.
