Pitcher Notes

Adam Mazur was by far the best starter on Tuesday night. His slider, which is his best pitch, generated eight whiffs, followed by his fastball which averaged 93.7 mph, topping out at 95.9 mph. Fish On First's #11 prospect generated 12 whiffs in total and earned the win for the Jumbo Shrimp.

One of the longest-tenured players in the Marlins organization, left-hander Luis Palacios continues to attack the strike zone. It was relievers Nigel Belgrave and Josh Ekness who stole the show. In one inning of work, Belgrave struck out the side, earning him the win. As for Ekness, he earned himself the save, striking four in 1 ⅔ innings pitched.

Emmett Olson kept the opposition hitless, but was limited to only two innings. FOF will provide an update as soon as possible regarding why he exited so early. Will Schomberg, who the Marlins acquired from the Seattle Mariners in the JT Chargois trade, stepped in and gave the Sky Carp three innings of work, allowing one run off of one hit, walking one and striking out six.

Every member of the Jupiter pitching staff had a hard time throwing strikes as they surrendered 22 walks on the night. Starter Juan De La Cruz walked five, two of the relievers both walked four and three other relievers each walked three.

Position Player Notes

First baseman Deyvison De Los Santos had a two-RBI game despite striking out two times. He has now struck out 18 times in nine games played thus far, tied for the highest total in the Marlins org. He's slashing .263/.317/.289/.606 with five RBI. He's yet to hit a home run. De Los Santos had the second hardest-hit ball (111.3 mph) of the night, just behind his teammate Agustín Ramírez (111.8 mph).

De Los Santos and Maximo Acosta were the only players with a multi-hit game for the Jumbo Shrimp.

Outfielder Jakob Marsee, who is ranked 24th on our prospect list, has ten stolen bases this season to lead Minor League Baseball. On Tuesday, he went 1-for-3 with a walk, strikeout and stole second and third base. He's now slashing .172/.400/.241/.641 with three RBI through nine games.

After a slow first series, Joe Mack had himself a three-hit game, with one of those as his first home run of the 2025 season. He finished the night going 2-for-3 with a home run, three RBI and scored two runs. He's FOF's #8 prospect. Cody Morissette and Nathan Martorella drove in runs for the Wahoos in their win over Montgomery, putting them at 4-0 on the season, the only undefeated Marlins affiliate.

It was a rough day for the Beloit lineup as they struck out 11 times, but did work seven walks. The only players who recorded base hits were Wilfredo Lara, Ryan Ignoffo, Brock Vradenburg and Emaarion Boyd. They still sent the potential tying run to the plate in the ninth inning, but fell short.

By far the most interesting stat line from Tuesday's slate belonged to FOF #2 prospect Starlyn Caba, who worked five walks with two steals. In addition to his excellent defense, Caba's plate discipline and speed made the Marlins interested in acquiring him over the offseason. He's currently sporting a .500 on-base percentage.

Outfielder Dillon Head extended his hit streak to four games and is now slashing .333/.316/.556/.872 with three RBI and three stolen bases this season. The only downside thus far has been he's struck out five times and has yet to work a walk.

Andrés Valor and Carter Johnson both knocked in a pair of runs for the Hammerheads late in their blowout loss.
