Christian Koss marked the conclusion of his rookie MLB season with a personal milestone, tattooing his last name and the MLB logo on his upper back in October, symbolizing the completion of his full season with the San Francisco Giants. Looking ahead to the 2024 season, Koss emphasized that his most significant offseason achievement was simply having time off to train, which allowed him to recover without the pressure of seeking playing time.
Offseason Training and Growing Strength Visible at Scottsdale Stadium
At 28, Koss spent his offseason training at Riverside Community College rather than participating in winter leagues as he had in past years. This rest and focused preparation paid off, evident during a recent scrimmage at Scottsdale Stadium where Koss hit an impressive opposite-field home run. He described this as his first true offseason, free from continuous instructs and winter ball assignments.
“It was the first offseason that I’ve really had an ‘offseason.’ There was no winter ball, I got actual weight room time,”
Koss said.
“When I was drafted, I went instructs, instructs, (Arizona) Fall League, Puerto Rico, Puerto Rico, Dominican Republic. This year I had a full offseason.”
Utility Player Role Strengthens Team Flexibility for Opening Day
Koss was the unexpected winner of the Giants’ bench competition last spring, and he enters the upcoming season with an advantage due to his adaptability. Alongside Casey Schmitt, he is likely to fill a backup infielder role; however, Koss’ comfort playing in the outfield adds valuable depth. This positional flexibility could prove crucial if Bryce Eldridge secures the designated hitter spot, limiting positional options elsewhere. Tyler Fitzgerald’s recent participation in outfield drills hints at the team’s emphasis on preparedness across multiple positions.

Versatility Rooted in Diverse Playing Experience
Koss’ experience playing in the Dominican Republic during previous winters helped develop his outfield skills, and he remains open to various roles. This versatility was underscored last year when Koss even pitched in several lopsided games. Giants’ staff member Tony Vitello highlighted Koss’ multifaceted background, noting early discussions about Koss’ previous defensive role as a catcher before transitioning into shortstop.
“Ultimately, what you’ve got is a very versatile guy,”
Vitello said.
“The best part about him is his teammates trust him. It’s one thing to be liked, but I think to be trusted and respected is more important, and he has that in the clubhouse.”
Injury Report Shows Positive Outlook for Giants’ Pitching Staff
Early injury concerns are minimal with right-hander Joel Peguero carrying the most notable issue—a tight left hamstring—though the team is taking a cautious approach. This limited number of injuries highlights the overall health of the Giants to this point in camp. Tyler Mahle, sidelined briefly by illness, is expected to face hitters soon as he continues his recovery.
Peguero impressed during his 2023 rookie campaign, posting a 2.42 ERA and a 3.85 FIP across 17 appearances, including a streak of nine scoreless outings to begin his major league career. Despite some inconsistency later, he ended the season strongly, positioning himself as a potential late-inning bullpen option amid the Giants’ shortage of experienced relief arms.
Meanwhile, several other relievers are in various stages of rehabilitation. Jason Foley is progressing well from right shoulder surgery and is slated for bullpen sessions soon but is unlikely to be available until midseason. Left-hander Sam Hentges, recovering from knee and shoulder surgeries, is working through a throwing program with uncertain readiness for Opening Day. Randy Rodriguez, out following Tommy John surgery, is expected to begin throwing next month.
Promotion of Dave Groeschner Brings Stability to Medical and Performance Department
The Giants recently elevated Dave Groeschner to vice president of medical and performance, a role reinforcing his three-decade-long commitment to the organization. Serving in leadership since 2007, Groeschner has been key to maintaining the team’s overall health, especially among pitchers, and played a critical part in Buster Posey’s recovery from a major ankle injury in 2011.
“I know firsthand the care and dedication that Gresch has for our players and organization,”
Posey said.
“We look forward to his continued influence in this new role.”
Looking Ahead to 2024 Season
Christian Koss’ expanded role and demonstrated flexibility provide the San Francisco Giants with crucial depth as they prepare for the 2024 campaign. His offseason strength gains and willingness to contribute at multiple positions give manager Tony Vitello valuable options during games. Alongside strong bullpen prospects like Joel Peguero and a revitalized medical team under Dave Groeschner’s leadership, the Giants are positioned for resilience and adaptability moving forward.
