Jonathon Long Makes For Stash Play in Deeper Leagues

Miami Marlins first base prospect Jonathon Long is coming off a two-homer game on Friday night and has had a pretty good statistical spell with the Triple-A Jacksonville Jumbo Shrimp since he was traded to the Marlins from the Chicago Cubs. In 24 games in Jacksonville, Long has three homers and 16 RBI to go with 23 runs scored and a .259 batting average. Long, who mostly plays first base, is the No. 19 prospect for the Marlins with a 50-grade hit tool and 50-grade power. Long had a nice season in the Cubs farm system prior to the trade with 12 homers and 62 RBI for the Triple-A Iowa Cubs with a .283 batting average. The 24-year-old could see a promotion in Miami late in the season with more likelihood than he had in the Chicago system. Long could be a sneaky stash play down the stretch in deep fantasy leagues.

Jonathon Long Fading from Stash Radar Amid Slump

Miami Marlins infield/outfield prospect Jonathon Long looked primed to make a major league debut in 2026, but has slowed down quite a bit at Triple-A since being traded to the Marlins, especially lately. The Marlins' 19th-ranked prospect is 6-for-42 (.143) over his last 13 games at Jacksonville, though he managed a 13:15 BB:K over that stretch. While that many walks is great (23.2 percent), that many strikeouts (26.8 percent) may hinder his chances of a late-season debut unless he turns things around in a hurry. The right-handed hitter batted .305 and popped 20 home runs last season, and is up to 13 in all this season with a .275 average through 119 games, so he offers a blend of contact and power that is intriguing for fantasy. However, the strikeout rate likely wouldn't improve in the majors, and were he to get called up, it might be on the short side of a platoon role, so without a clear path to at-bats, the 24-year-old should be left on the waiver wire in most leagues.

Jonathon Long Looks More Like Dynasty League Addition

Miami Marlins corner infield prospect Jonathon Long has played 18 games for Triple-A Jacksonville since he was traded to the Marlins from the Chicago Cubs at the trade deadline. In those 18 games, Long has one homer and nine RBI to go with 16 runs scored and a .246 batting average. Before the trade, in 99 games with Triple-A Iowa, Long hit .283 with 12 homers and 62 RBI. Long is the No. 19 prospect in the Marlins' organization and has a 50-grade hit tool with 50-grade power. Miami has good depth around the board so it might be tough for Long to break through with the big-league club this season. But the 24-year-old right-handed hitter has good potential in dynasty league formats and looks more likely to make it to the big leagues following the trade deadline deal.

Jonathon Long Could Be Sneaky Late-Season Stash Candidate

Miami Marlins first base/outfield prospect Jonathon Long has played 16 games with Triple-A Jacksonville after being traded over from the Chicago Cubs. Long has managed one homer and seven RBI while hitting .260 to go with 16 runs for his new club. With Triple-A Iowa before his trade, Long was hitting .283 with 12 homers and 62 RBI to go with 67 runs in 99 games. Long slots in as the No. 19 prospect with Miami but could see some time with the Marlins when rosters expand. The path to the majors has gotten clearer for Long since the trade deadline, and he could get a September shot with the Marlins, which would have been unlikely with the Cubs. Long has a 50-grade hit tool and 50-grade power. He could be a sneaky late-season addition to fantasy rosters.

Jonathon Long With Shot at Marlins Debut This Season

Miami Marlins infield/outfield prospect Jonathon Long has four RBI and 14 runs scored in 13 games since joining Triple-A Jacksonville. Long was acquired by the Marlins from the Chicago Cubs at the trade deadline. In 99 games this season with Triple-A Iowa, Long hit .283 with 12 homers and 62 RBI to go with 67 runs scored. The 24-year-old infield/outfield prospect is the No. 19 prospect in the Marlins' system and has a 50-grade hit tool with 50-grade power. Long has the versatility to play either corner infield position along with the outfield, giving him a better shot at making his debut this season. With first baseman Kyle Stowers on the IL, that also gives Long a better shot at an MLB debut. The Marlins do have good outfield depth, along with Javier Sanoja manning third base, so Long will need to break through a bit for a big-league opportunity this season.

Jonathon Long Has Skills to be a Productive Major-League Player

In 10 games with his new organization, Miami Marlins corner-infield prospect Jonathon Long has fared well at Triple-A Jacksonville, hitting 9-for-28 (.321) with three RBI and 11 runs scored. Long came over to the Marlins organization after spending the beginning of the season in the Cubs system. He played all year prior at Triple-A Iowa and hit .283 in 99 games and hit 12 homers with 62 RBI and 67 runs scored. Now with Miami, Long, a right-handed hitting third or first base prospect, has a clearer path to big-league playing time. He is the No. 19-ranked prospect in the Marlins' system after the trade and at 24 years old, could get a look at an MLB debut, especially with first baseman Kyle Stowers on the IL. Long has a 50-grade hit tool with 50-grade power and could be an impact bat for the Marlins and for fantasy teams down the stretch.

Jonathon Long Has Clear Path To Major League At-Bats With New Team

In nine games with his new squad, the Triple-A Jacksonville Jumbo Shrimp, Miami Marlins corner-infield prospect Jonathon Long is 9-for-25 (.360) at the plate with three RBI and 11 runs scored. The right-handed hitting third base/first base prospect was traded from the Chicago Cubs organization to the Marlins. He started at Triple-A Iowa with 12 homers and 62 RBI in 99 games with a .283 average and 67 runs scored. Long slots in at the No. 19 prospect in the Marlins system, but he might have a clearer path to the majors than he did with the Cubs. The Marlins are playing Javier Sanoja at third base and now have Kyle Stowers on the IL at first base. So there looks to be an opportunity for Long to make his big-league debut. If he does, he would be a solid bat for fantasy managers down the stretch.

Jonathon Long Could Debut with New MLB Club Down the Stretch

According to Christina De Nicola of MLB.com, recently acquired first base prospect Jonathon Long could debut with the Miami Marlins later in the second half. De Nicola reports that Long, who was shipped to Miami ahead of the trade deadline, "should receive a callup by season's end if he continues to produce." Long joined the Marlins in the trade that sent left-handed pitcher Braxton Garrett to the North Side of Chicago. With Iowa this season, Long was very productive, posting a .283/.364/.455 line with a .819 OPS, 30 doubles, 12 home runs, and two stolen bases. Since joining Triple-A Jacksonville, Long has held a stellar .386 AVG through five games. With Miami struggling to hit southpaws, the right-handed power bat would provide a much-needed spark to their lineup.

Jonathon Long Looks To Make Waves With New Organization in Majors

Miami Marlins first base/outfield prospect Jonathon Long is looking to jump-start his career after being traded to the Marlins from the Chicago Cubs at the trade deadline. Long was productive this season for Triple-A Iowa in the Cubs organization, playing 99 games and hitting .283 with 12 homers and 62 RBI to go with 67 runs scored. Long has been assigned to Triple-A Jacksonville after coming over to the Marlins. He slots in as the No. 14 prospect with the Marlins and has a 55-grade hit tool with 50-grade power. The 24-year-old right-handed hitter can play first base or the outfield, giving him added versatility for a potential call-up to the Marlins. The Marlins have some decent outfield and first base depth but could look to Long for some added firepower with the bat this year. Long is a solid stash with a decent path to some playing time at the big league level.

Jonathon Long Has Clearer Path To Majors After Trade to Miami

The Miami Marlins acquired first base prospect Jonathon Long from the Chicago Cubs in exchange for pitcher Braxton Garrett. Long slots in as the No. 14 prospect in the Miami system and could see time in the majors for the Marlins this season. Right now, Kyle Stowers leads the depth chart at first base for the Marlins at the major league level, but Long could provide some depth this season and also could slot in at one of the outfield spots if needed. Long has a 55-grade hit tool with 50-grade power and hit .283 for the Triple-A Iowa Cubs with 12 homers and 62 RBI in 396 at bats. The 24-year-old added 67 runs scored for Iowa. He is a name to stash in fantasy following his change of scenery and he could see time in the majors in his age 24 season in he second half of this year.
