Christian Koss

Giants Place Matt Chapman On 10-Day Injured List

By Nick Deeds | June 10, 2025 at 8:54pm CDT

The Giants announced today that they’ve placed third baseman Matt Chapman on the 10-day injured list with a sprained right hand. Infielder Christian Koss was recalled to the club’s roster to replace Chapman. The infielder spoke at length Susan Slusser of the San Francisco Chronicle and Maria Guardado of MLB.com about his injury, noting that he’s certain to miss more than the minimum ten days after injuring his hand while diving towards third base in the eighth inning of the club’s game on Sunday.

Chapman indicated that he’s suffering from sprains in three of the fingers on his right hand, and each of those three fingers also has a bone bruise. The third baseman’s exact timeline for return is not yet clear, but he said he hopes to be back in action before the end of the first half. That suggests he hopes to return at some point before the All-Star break begins on July 14, although Slusser adds that Chapman is set to meet with hand specialist Dr. Steven Shin in Los Angeles on Friday and that the team will know more about his exact timeline for return after that meeting.

Even a few weeks without Chapman would be a frustrating bump in the road for a Giants team that has managed to outperform expectations in a big way this year, as they currently sit just 1.5 games back of the Dodgers in the NL West and firmly entrenched in the Wild Card mix. Chapman’s been a major part of that success so far, as he’s slashed an excellent .243/.360/.452 with a wRC+ of 134 while playing his typical excellent defense at the hot corner. That package has been enough to generate 2.5 fWAR in just 65 games, a figure that just nine players in the NL have managed to top so far this season. On top of his excellent season-long production, the veteran was also in the midst of a particularly hot stretch as he had been hitting .322/.429/.610 with a wRC+ of 194 over his past 17 games.

Replacing Chapman on the roster is Koss, who made his big league debut for San Francisco earlier this year. He hasn’t hit much in the majors yet, with a career slash line of just .219/.275/.266 (57 wRC+) across 29 games. Koss is an impressive and versatile defender, however, and he’ll likely slide into the utility role Casey Schmitt was previously getting used in while Schmitt takes over for Chapman at the hot corner. The 26-year-old seemed to enjoy something of a breakout last year when he posted a 109 wRC+ in 40 games, but this year he’s hit just .180/.281/.240 across 20 games despite fairly strong peripheral numbers. Perhaps sliding into an everyday role while Chapman is out of commission will give Schmitt the opportunities he needs to play closer to his peripheral numbers, which suggest he can be an average-to-above average hitter in the majors if he can turn that underlying performance into on-field production.

Giants Designate LaMonte Wade Jr., Sign Dominic Smith

By Steve Adams | June 4, 2025 at 11:38am CDT

The Giants are shaking up their struggling offense. The team announced Wednesday that first baseman LaMonte Wade Jr. and backup catcher Sam Huff have been designated for assignment. Veteran first baseman Dominic Smith, who recently opted out of a minor league deal with the Yankees, has been signed to a one-year, major league contract. San Francisco also selected the contracts of outfielder Daniel Johnson and catcher Andrew Knizner from Triple-A and optioned infielder Christian Koss.

After a hot start to the season, the Giants have dropped 14 of their past 23 games. The offense has been the primary culprit, particularly over the past two weeks. Over the past 14 days, Giants hitters have posted a combined .209/.297/.306 batting line. They haven’t scored more than four runs in a game since May 16 and have been shut out or held to one run seven times in that span.

Wade’s struggles have been a major component of the team’s offensive drought, but unlike many of his teammates, the 31-year-old veteran has simply never gotten going in 2025. Wade was hitless in his first 18 trips to the plate this season and hasn’t pulled himself out of that funk. He’s batting .167/.275/.271 on the season and is currently in the midst of a 3-for-22 skid.

It’s been a swift and fairly shocking decline for Wade, who was a solidly above-average bat for San Francisco from 2021-24. He’s been the Giants’ primary first baseman in that stretch, and while he’s never been a huge power threat, he’s been an on-base machine. Wade was one of the best acquisitions of the Farhan Zaidi era in San Francisco, coming over from the Twins in a Feb. 2021 trade that sent righty Shaun Anderson to Minnesota. The swap drew minimal attention at the time, but Wade went on to bat .248/.352/.415 in his first four years as a Giant.

As recently as last season, Wade slashed .260/.380/.381 with a massive 15.5% walk rate. He’s been heavily platooned in his career, taking just 12% of his plate appearances against lefties and slashing .193/.288/.250 in that time, but Wade has been consistently productive against righties until 2025.

Wade’s 2025 struggles seem to stem from a loss of bat speed and, accordingly, pronounced troubles against velocity. He punished four-seamers from ’21-’24 but is hitting just .164 with a .262 slugging percentage against them in 2025. Statcast measured Wade’s bat speed at 73.8 mph in 2023 and 72.4 mph in 2024; he’s down to 69.7 mph in 2025, which places him in the 18th percentile of big league hitters.

Wade is still drawing walks at an outstanding 12.4% clip, and his 18.1% chase rate on pitches off the plate is the sixth-lowest among the 220 MLB hitters with at least 150 plate appearances this season. It’s clear that he has excellent pitch recognition and is still making good swing decisions — he’s just not doing any damage when he does make those correct choices.

In Wade’s defense, his .211 average on balls in play is more than 70 points shy of league-average. That can’t be entirely explained by bad luck, however, as he’s currently sporting a career-high 47.3% fly-ball rate. Fly-balls that stay in the yard are easier to convert into outs than grounders and especially line-drives, so even there’s unquestionably been some bad luck at play, Wade’s current batted-ball profile shouldn’t portend a rebound all the way back to his career .279 BABIP. That’s especially true given that he’s already hit more harmless infield pop-ups (six) through 169 plate appearances than he did in all of 2024 (four) in 401 trips to the plate.

Wade is being paid $5MM and is a free agent at season’s end. There’s still about $3.12MM of that sum that’s yet to be paid out. That figure could make it hard to find a trade partner, though the Giants could pay down a portion of the salary if another team has some interest.

The remaining money on Wade’s contract might be steep enough to allow him to pass through waivers if the Giants go that route, as any team that claimed him would take on that full $3.12MM (or a bit less, depending on the date he’s actually placed on waivers). If Wade were to clear, he has enough service time to reject a minor league assignment and retain the rest of that guaranteed money. In that scenario, any club that signs him would only need to pay him the prorated league minimum. That’d be subtracted from what the Giants owe him, but San Francisco would still be on the hook for the rest of his salary.

For at least the time being, Wade will be replaced by Smith. The former first-round pick is a veteran of eight big league seasons but has seen his offense drop after a huge 2019-20 showing wherein he batted .299/.366/.571 in 396 plate appearances with the Mets. Smith has begun to slip into journeyman status; the Giants are his seventh organization since 2022.

However, even though Smith has bounced around the league, he’s managed to deliver passable, if unspectacular offense in each of the past two seasons. Over 893 plate appearances between the Nationals, Red Sox and Reds, he’s slashed a combined .247/.321/.370. That’s about 8% worse than average, by measure of wRC+, but is still miles better than what Wade has produced so far in 2025. Smith was hitting decently with the Yankees’ Triple-A affiliate in Scranton, slashing .255/.333/.448 with eight homers in 189 turns at the plate.

In all likelihood, Smith will be a placeholder at first base. Top prospect Bryce Eldridge was promoted from Double-A to Triple-A yesterday and shouldn’t be too far from getting a look in the majors. The 2023 first-rounder is still only 20 years old, but you wouldn’t know it when taking a look at the .280/.350/.512 line (147 wRC+) he produced against older, more experienced competition in Double-A this year. Eldridge is widely regarded as one of baseball’s 25 best prospects, and once he gets a call to the majors, he’ll get everyday at-bats at first base. Smith could hang around in a bench role if he’s hitting well enough, but Eldridge is considered San Francisco’s first baseman of the future and shouldn’t be long for the minors.

Huff, 27, has appeared in 20 games this year and only tallied one multi-hit effort. In 58 plate appearances, he’s turned in a .208/.259/.340 batting line with a huge 43.1% strikeout rate. The former Rangers top prospect has struggled to make contact throughout his limited run in the majors over the years. Huff entered 2025 with a career 33.6% strikeout rate in 214 plate appearances at the MLB level.

Patrick Bailey is entrenched as the Giants’ starter behind the plate and is among the sport’s best defenders at any position, but he’s struggling with the bat as well (.191/.254/.276). Bailey is so good defensively that the Giants aren’t going to make any changes there, but with their catcher batting an MLB-worst .191/.253/.291, they’ll shuffle things up on the reserve side and hope for a bit more offense from Knizner.

Knizner, 30, isn’t a great hitter himself. He’s a career .210/.279/.317 hitter in 887 major league plate appearances. That said, his career 23% strikeout rate is markedly lower than that of Huff. Knizner isn’t as well regarded from a pitch-framing standpoint, but Statcast gives him much better grades than Huff when it comes to blocking balls in the dirt.

Knizner has also had a massive showing in Triple-A this year, batting a combined .378/.512/.520 with more walks than strikeouts in 129 plate appearances between the top affiliates for the Nationals and the Giants. No one would realistically expect him to maintain even 75% of that pace in the majors, but given Huff’s struggles and the broader-reaching difficulties incurred by the Giants’ lineup as a whole, it’s not a surprise that Knizner’s eye-popping numbers earned him a bump to the big leagues.

Rounding out today’s influx of new bats in the Giants clubhouse is Johnson, whom they signed out of the Mexican League earlier this season. As was the case with Jerar Encarnacion in 2024, Johnson posted video game numbers in Mexico (.429/.512/.943) and caught the eye of Giants scouts. He’s been quite good since signing back on May 2, hitting .272/.312/.534 with six homers and five steals in 109 plate appearances. He’s seen brief MLB time with the Guardians and Orioles but has only 95 big league plate appearances to his credit. Johnson has a solid Triple-A track record, having slashed .257/.323/.452 in parts of six seasons.

Giants Select Christian Koss

By Anthony Franco | March 26, 2025 at 7:46pm CDT

The Giants announced that they’ve selected infielder Christian Koss onto the 40-man roster. He’ll break camp and will make his major league debut once he gets into a game. San Francisco optioned Grant McCray and Brett Wisely while reassigning non-roster invitees Joel Peguero and Max Stassi to Triple-A Sacramento. The Giants also placed Jerar Encarnacion on the 10-day injured list with a fracture in his left hand that’ll require surgery. They placed catcher Tom Murphy on the 60-day injured list to open a 40-man roster spot for Koss.

Koss, 27, is entering his second season in the San Francisco organization. The Giants acquired him from the Red Sox in a minor league deal on the eve of the ’24 campaign. It was the second trade of his career. Koss was initially a 12th-round pick by Colorado and went to the Red Sox in a minor trade in 2020. He reached Triple-A in the Boston system before being traded.

The UC-Irvine product divided his first season with San Francisco between the top two minor league levels. He raked at a .386/.453/.627 clip over 25 Double-A games but posted a more modest .257/.332/.415 line across 197 Triple-A plate appearances. Koss played quite well in Spring Training, hitting .341 with five walks and seven strikeouts through 47 trips to the plate. He can bounce around the infield and provides a speed element off the bench. Koss and Casey Schmitt will work as utility players behind Tyler Fitzgerald, Willy Adames and Matt Chapman.

Murphy, who has dealt with plenty of injuries throughout his career, is currently shelved with a herniated disc in his back. He has received multiple epidural injections. He’ll miss at least the first two months of the season. Sam Huff will begin the season as the backup catcher behind Patrick Bailey.

Giants Notes: Stassi, Huff, Villar, Schmitt

By Mark Polishuk | March 23, 2025 at 10:57pm CDT

Max Stassi won’t exercise the opt-out clause in his minor league contract, Susan Slusser of the San Francisco Chronicle writes, and the catcher will instead remain in the Giants organization and play with Triple-A Sacramento.  Yesterday marked the first of three opt-out dates automatically included in Stassi’s contract due to his Article XX(b) free agent status, and Stassi’s next chance to evaluate his future will come on May 1 if he hasn’t yet been added to the Giants’ roster.

There apparently wasn’t much drama in the competition between Stassi and Sam Huff to be Patrick Bailey’s backup catcher, as Slusser notes that Stassi “has known the plan for a while and is fine with it.”  If anything, playing in Sacramento has particular appeal for the catcher because he lives in the city and can spend more time with his family.  Playing in the minors also allows Stassi the more regular on-field action he needs to ramp up after undergoing hip surgery last year.

Tom Murphy will miss the start of the season due to a herniated disc, creating the opening for Huff to eventually win the backup job.  Formerly a top prospect in the Rangers’ farm system, Huff’s defense was often called as a question to stick in the catching role, and Jonah Heim ended up passing Huff on the depth chart.  After Huff’s numbers dropped off at Triple-A last year, Texas designated the backstop for assignment, and the Giants claimed him away off waivers in January.  The change of scenery seems to have helped thus far, as Huff has been tearing it up at the plate in the Cactus League.

The rest of San Francisco’s bench mix has yet to be determined, though Luis Matos will likely claim the backup outfielder role.  Since it doesn’t seem like Jung Hoo Lee’s recent back issue is serious (“I don’t even want to use the word injury, it was so mild,” Lee told Slusser and other reporters), the Giants could take two infielders from the group of Casey Schmitt, Brett Wisely, David Villar, and prospect Christian Koss.

Villar seems to be the odd one out, as Slusser feels the Giants will be designating him for assignment this week since Villar is out of minor league options.  The infielder hit a respectable .231/.331/.455 over 181 plate appearances in his 2022 rookie season, but then struggled badly over 140 PA in 2023 and seemed to fall out of favor for playing time.  Villar has a very impressive .268/.377/.511 slash line and 60 homers over 1182 career Triple-A plate appearances, with the caveat that that production came in Sacramento in the hitter-friendly Pacific Coast League.  A rival team in need of infield depth might be impressed enough by those numbers to take a flier on Villar if he does up on the waiver wire in the coming days.

There would seemingly be a lot more interest if the Giants made Schmitt available, as Slusser reports that multiple teams have expressed trade interest this offseason.  The Giants, however, don’t have much interest in moving Schmitt, who is still two seasons away from even gaining arbitration eligibility.  He also has one minor league option year remaining, giving the Giants flexibility in sending him back and forth from Triple-A.

Schmitt has a good track record of Triple-A results, and he showed improvement at the big league level in 2024, albeit in significantly fewer at-bats than he received in his 2023 rookie season.  Schmitt hit .206/.255/.324 in 277 PA in 2023, and then bumped that up to a .252/.283/.477 slash line over 113 PA last year.  In theory, Schmitt should again see limited action now that Willy Adames was signed to bring more stability to San Francisco’s infield, which in turn bumped Tyler Fitzgerald into a regular second-base role.

Minor MLB Transactions: 12/3/20

By Connor Byrne | December 3, 2020 at 10:00pm CDT

The latest minor moves from around baseball…

  • The Rays have signed righty David Hess to a minors deal, Marc Topkin of the Tampa Bay Times tweets. The Orioles, who chose Hess in the fifth round of the 2014 draft, outrighted him in October. He debuted in the majors in 2018 and has since recorded a 5.86 ERA/6.41 FIP with 6.76 K/9 and 3.26 BB/9 in 190 1/3 innings.

Earlier transactions:

  • The Rockies announced that they have acquired left-hander Yoan Aybar from the Red Sox for infielder Christian Koss. Aybar, now 23, didn’t produce much as an outfielder through 2017, which led the Red Sox to move him to the mound. With a fastball that can reach triple digits, Aybar pitched to a 4.61 ERA with 11.1 K/9 and 6.5 BB/9 in 56 2/3 innings between the Single-A and High-A levels in 2019. Koss, who will turn 23 in January, was a 12th-round pick of the Rockies in 2019 who hasn’t gotten past rookie ball. He did perform very well there during his first pro season, though, as he slashed .332/.447/.605 with 11 home runs in 238 plate appearances.
  • The Brewers tweeted that they’ve signed third baseman Zach Green to a minor league contract with an invitation to big league camp. The 26-year-old was a third-round pick of the Phillies in 2012 who spent the previous two seasons in the Giants organization. Green made his MLB debut in 2020 and totaled 16 plate appearances, though he picked up just two hits. However, Green isn’t far removed from an excellent 2019 showing in Triple-A, where he slashed .282/.380/.659 with 25 home runs in 297 plate appearances.
  • Right-hander Zach Thompson announced on Twitter that he has signed with the Marlins. It’s presumably a minors deal for Thompson, who had been with the White Sox since they selected him in the fifth round of the 2014 draft. The 27-year-old topped out in Triple-A ball in 2019 with 70 1/3 innings of 5.50 ERA ball. While Thompson had difficulty preventing runs then, he did post impressive strikeout and walk numbers (10.0 K/9, 2.9 BB/9).
  • The Pirates outrighted first baseman/outfielder Will Craig to Triple-A Indianapolis on Wednesday, Adam Berry of MLB.com tweets. Craig joined the Pirates as a first-rounder in 2016, but his major league impact has been minimal to this point. He collected four plate appearances in his Pittsburgh debut last season, but he went hitless in that short span and the Pirates designated him for assignment last week. In his most recent minor league action, in 2019, the 26-year-old batted .249/.326/.435 with 23 homers across 556 plate appearances at the Triple-A level.
