Marlins injury updates: Deyvison De Los Santos suffers quad strain, Victor Mesa Jr. reinstated from IL

On Saturday, Fish On First's number 19 prospect Victor Mesa Jr. was reinstated from the 7-day injured list. Unfortunately, the corresponding roster move for the Jacksonville Jumbo Shrimp was placing Deyvison De Los Santos (FOF #9) on the 7-day IL.

Mesa suffered a right hamstring strain during spring training and did not appear in any Grapefruit League games. He later had warts on the bottom of his foot surgically removed, which elongated his IL stint.

Mesa had been emerging as a serious call-up candidate during the 2024 season. He played in 80 Triple-A games and slashed .259/.319/.430/.749 with 13 home runs, 51 RBI and a 98 wRC+. Defensively, he played primarily center field, but saw action in all three spots. Mesa suffered a back injury in late July and missed the rest of the year.

Mesa is batting leadoff and playing center field in his 2025 Jumbo Shrimp debut.

De Los Santos, who the Marlins acquired last season from the Arizona Diamondbacks, was Minor League Baseball's reigning home run king. He got off to a slow start in 2025, but recently caught fire with two homers and a 1.154 OPS in five games prior to getting hurt. Considering the struggles of Matt Mervis, the 21-year-old first baseman was beginning to emerge as an alternative for the Marlins. For the season, he is slashing .250/.317/.399/.716 with five home runs and 20 RBI.

During Friday's game, De Los Santos suffered a left quad strain running to first base in the top of the second inning. This is the first IL stint of his professional career.

Longtime Marlins prospect Troy Johnston has been splitting time between left field and first base this season. He will now likely see almost all of his reps at first. He is slashing .273/.357/.491/.848 with four home runs, 19 RBI and 13 stolen bases. A former Marlins Minor League Player of the Year who is six years older than De Los Santos, he has made an even stronger case to potentially be called up. He is hitting fifth in Saturday's Jumbo Shrimp lineup.
