The next chapter for Marlins' Jakob Marsee is unfolding, and it's a compelling one. On the day the team kicked off spring training and finalized a contract with seasoned left-handed reliever John King, several intriguing updates about the team emerged.
To start, center fielder Jakob Marsee has made quite an impression, arguably having the most remarkable debut month of any rookie in Marlins history, aside from Dontrelle Willis (who had a stellar 14-6 record with a 3.30 ERA during his rookie year). When Marsee was promoted from Triple-A Jacksonville on August 1, he immediately became a force to be reckoned with, boasting an impressive .352 batting average along with a .430 on-base percentage. In just 30 games throughout August, he hit four home runs, drove in 25 runs, and swiped nine bases.
His debut was nothing short of historic; he became the first player in Marlins history to reach base four times in his first game. Additionally, he tied a franchise record by driving in seven runs in a single game on August 13 against Cleveland. Marsee joined the elite company of Giancarlo Stanton and Miguel Cabrera as one of the few Marlins under the age of 25 to achieve over 35 hits and more than 25 RBIs within a single month.
However, September proved to be a different story for Marsee. The last five weeks of the season showcased rookie-like struggles, with him posting a .231 batting average, a .292 on-base percentage, one home run, and eight RBIs across 25 games.
Despite finishing the season with commendable overall stats (.292 batting average, .363 on-base percentage, five home runs, 33 RBIs, and successfully stealing 14 out of 20 attempts in 55 games), the slower conclusion to his season prompted Marsee to reflect on necessary adjustments—though he emphasized the importance of not overreacting to the evolving strategies of opposing pitchers.
"Every week they were pitching me differently," Marsee shared last week. "The key for me is not to overadjust. At times, I found myself making excessive changes, which allowed them to exploit certain weaknesses."
He noted that while he was focused on covering outside pitches, he became vulnerable to fastballs on the inside. His resolution? “I can handle both types of pitches as long as I'm grounded in my approach, so there’s no need to cheat.” He expressed a desire for greater consistency based on the lessons learned from his earlier difficulties.
Manager Clayton McCullough sees a bright future for Marsee, stating, "He will need to keep adjusting to the league. His baseline performance is incredibly high thanks to his defensive skills and base-running capabilities. He has a good command of the strike zone. As the league adapts, Jakob's elevated performance level will prompt different discussions during pregame and preseason meetings."
In other news:
*Shortstop Otto Lopez, who had a breakout season last year with 15 home runs, 77 RBIs, and a .303 on-base percentage, is aiming to enhance his defensive game as he embarks on his first full year as a shortstop. He has been analyzing footage of standout players, including Francisco Lindor from the Mets and Bobby Witt Jr. of Kansas City. Lopez also reviewed his own gameplay from last season, determined to improve his range, throwing accuracy, and overall positioning.
Despite committing 10 errors in 111 games at shortstop after switching positions with Xavier Edwards in late May, Lopez still ranked fourth in defensive wins above replacement when considering his time at second base. "I genuinely enjoy playing shortstop, and I believe I can perform much better this year," he stated confidently.
*Marlins President of Baseball Operations Peter Bendix reiterated the team's commitment to keeping their top talent, stating at FanFest, "We intend to offer contract extensions to several of our best players. Our goal is to retain these exceptional athletes for as long as we can. We anticipate having many of them around for a significant period."
*Victor Mesa Jr. quietly concluded his tenure with the Marlins, having been traded to Tampa Bay after being designated for assignment. In exchange, the Marlins received minor-league shortstop Angel Brachi, who had an impressive .337 batting average and a .453 on-base percentage in the Dominican Summer League last season. Notably, Brachi led all rookie-level players with 30 hit-by-pitches since 2024. Rated as Tampa Bay's 49th-best prospect by Fangraphs prior to last season, Brachi was part of the Rays' international signing class, receiving an $800,000 contract.
The Marlins originally signed Mesa Jr. and his brother Victor Victor Mesa during the much-publicized 2018 international signing period, offering them a combined total of $6.25 million in bonuses—$5.25 million for Victor Victor and $1 million for Mesa Jr. Despite being one of the top international prospects at the time, Victor Victor never made it to the majors and left the Marlins organization in 2023 after achieving only a .233 average across 290 minor-league games. Meanwhile, Mesa Jr. played 16 big-league games last season, hitting .188 with one home run and six RBIs.
Ultimately, what was once celebrated as a major signing during Derek Jeter's tenure as CEO has not yielded the anticipated results.
