Karson Milbrandt Yet to Hit Stride at Triple-A

Miami Marlins pitching prospect Karson Milbrandt has been a bit better lately, but it's been a struggle for him since being promoted to Triple-A Jacksonville. In 10 starts for the Jumbo Shrimp, Milbrandt is 0-5 with a 7.65 ERA. The talented right-hander dominated at Double-A Pensacola for much of this season but the results haven't followed him to Triple-A. That leaves a promotion to the Marlins as a little bit of a concern as the organization would like to see better results in the high minors. Milbrandt is still the Marlins' No. 5 overall prospect and has a high-profile three-pitch mix with 55-grade pitches in his fastball curveball, and slider. But for the most part he's been hit hard at Jacksonville. At age 22, there is plenty of time for growth but that might not be at the big league level until at least next season.

Karson Milbrandt Trending in the Wrong Direction at Triple-A

Miami Marlins pitching prospect Karson Milbrandt will get another opportunity to right the ship at Triple-A Jacksonville when he makes his next start for the Jumbo Shrimp this coming Saturday. The Marlins' fourth-ranked prospect pitched well enough at Double-A earlier this year to earn a promotion to Triple-A in early June, and after looking good for three starts, the right-hander has now allowed three earned runs or more in each of his last seven appearances, posting a gaudy 12.49 ERA, 2.51 WHIP, -4.1 percent K-BB%, and allowing opponents to hit a whopping .344 off him over that span. After looking like a lock to debut earlier this season with the big-league rotation very much in need of help, that is looking more like a long shot at this point. If the 22-year-old can string together a couple of consecutive good outings, then perhaps that outlook changes, but at this point, there isn't a need to stash him in redraft leagues.

Karson Milbrandt Drops Off Stash Radar With Latest Rough Outing

Miami Marlins pitching prospect Karson Milbrandt's rough showing at Triple-A continued with his latest start this past Saturday, when he allowed four earned runs on four hits and five walks while striking out three in two innings of work. The Marlins' fourth-ranked prospect looked good over his first three starts at Jacksonville, but has allowed four runs or more in five of his last seven appearances. It has resulted in a 7.96 ERA, 2.01 WHIP, and an ugly -0.6 K-BB% over 37 1/3 innings pitched. An MLB debut looked all but inevitable earlier this year, but with an opponent batting average of .285 at Triple-A and command that clearly needs some fine-tuning, his chances of a 2026 debut are fading quickly. Perhaps there is still time to earn a September call-up, but for now, there is little reason to stash the 22-year-old in redraft leagues.

Karson Milbrandt Has Been Hit Hard in August at Triple-A

Miami Marlins pitching prospect Karson Milbrandt has given up 11 combined earned runs in his last two August starts for Triple-A Jacksonville to bring his record to 0-5 in his last six starts. The right-handed pitcher is clearly talented but has found the going tough at Jacksonville. In Double-A Pensacola prior to his promotion, Milbrandt was 4-1 with a 1.34 ERA and 1.00 WHIP, but he's yet to find a win at Jacksonville. Despite his struggles, Milbrandt is ranked as the No. 4 overall prospect for the Marlins and has four 55-graded pitches in his fastball, curveball, slider, and cutter. Milbrandt might need to work through his struggles that he is experiencing in his first taste of Triple-A. He is still a highly ranked prospect and could debut for Miami at some point next season.

Karson Milbrandt Trending in the Wrong Direction, Falls From Stash Radar

Miami Marlins pitching prospect Karson Milbrandt has fallen on hard times after a strong start to the season. The Marlins' fourth-ranked prospect began the year with a 1.31 ERA, 1.06 WHIP, and a 23.6 percent K-BB% over his first 12 starts, which included three starts at Triple-A, but since then he owns an 11.95 ERA, 2.31 WHIP, and a shocking -2.8 percent K-BB% (he's walking more batters than he is striking out) over his last five starts. The right-hander was seemingly on the precipice of a major league debut in June, but after his latest outing in which he yielded seven earned runs on seven hits (three home runs), two walks, and one hit batsman, it looks like hopes of a 2026 debut are fading fast. If he can right the ship and string together a couple of good outings, starting with his next start this Saturday, perhaps a 2026 debut will be back in play, but it will likely be too late to help fantasy managers. The talented 22-year-old is worth monitoring, but for now, he's off the stash radar.

Karson Milbrandt Struggling To Find Consistency at Triple-A

Miami Marlins pitching prospect Karson Milbrandt has flashed his potential in his age 22 season, but has struggled with his control since joining Triple-A Jacksonville. In 27 innings pitched for Jacksonville, Milbrandt has walked 24 batters and has allowed 17 earned runs. It's been a bit of a struggle for Milbrandt to find the form he showed at Double-A Pensacola, but he is still ranked as the No. 4 prospect in the Marlins' system. At Pensacola, Milbrandt was 4-1 with a 1.34 ERA and 1.00 WHIP with 70 strikeouts in 47 innings. The strikeout rate was a product of his potential but Milbrandt hasn't found that same rate at Jacksonville. Milbrandt is worth looking at in dynasty leagues but might be best left on the waiver wire in redraft leagues as he works through some of his struggles.

Karson Milbrandt Needs to Improve Control Before Making Big-League Mark

In three July starts, Miami Marlins pitching prospect Karson Milbrandt has struggled a bit at Triple-A Jacksonville. His latest outing on July 18 saw him go four innings and give up three earned runs with five strikeouts and two walks. It was an improvement on his previous two July outings in which he combined for nine earned runs in just 3 2/3 total innings. All in all, a 14.09 ERA in July is not what you want to see, but he is still rated as the No. 4 overall prospect for the Marlins. The right-hander has four plus pitches with a 55 grade but struggles with overall control and is graded out at 40 for control. Milbrandt has flashed his potential with 95 total strikeouts in 74 innings between Double-A Pensacola and Jacksonville. The high strikeout rate is desirable for fantasy purposes but it might not be until next year that managers get to see Milbrandt make a difference at the big league level. He has plenty of potential but needs to work on his command in the minors.

Karson Milbrandt Remains High on Stash Rankings Despite July Blip

In two July starts, Miami Marlins pitching prospect Karson Milbrandt hit a bump in the road at Triple-A Jacksonville, allowing nine earned runs over 3 2/3 innings pitched. It's simply a bump in the road, because Milbrandt has been very good in the minors over the rest of the season. In four total June starts for Jacksonville, Milbrandt allowed a total of five earned runs over 19 1/3 innings pitched. Between Double-A Pensacola and Triple-A Jacksonville, Milbrandt has recorded a 4-3 overall record with a 2.70 ERA and 1.29 WHIP over 70 innings pitched with a whopping 90 strikeouts. The strikeout rate, compiled mainly at Pensacola, is elite and is very enticing for fantasy managers in search of starting pitchers. Milbrandt, the Marlins' No. 4 overall prospect, has four elite pitches, but his control needs work according to his scouting grades. With the quality strikeout rate and four top-notch pitches, Milbrandt has the looks of a successful fantasy option and should be in serious contention for a second-half promotion.

Karson Milbrandt Still a Top Stash Option Amid Triple-A Struggles?

Miami Marlins starting pitching prospect Karson Milbrandt is making a strong case for a promotion to the big league club despite two rough starts at Triple-A Jacksonville in his latest outings. Milbrandt has pitched well at two levels this year, going 4-1 at Double-A Pensacola with a 1.34 ERA and 70 strikeouts in 47 innings. Then he has gone 0-2 with a 5.48 ERA and 20 strikeouts in 23.0 innings pitched for Jacksonville. The Jacksonville numbers are slightly concerning for the 22-year-old right-hander, especially the nine earned runs he has given up in his last two starts. The numbers at Double-A and his prospect pedigree as the Marlins No. 4 overall prospect make him a desirable waiver-wire option as he waits for his shot to prove himself in Miami. With Eury Perez and Janson Junk healthy again, the Marlins rotation is at capacity right now, but a good stretch in the second half at Jacksonville could give Milbrandt a chance to show off his skills in Miami.

Could Marlins Give Karson Milbrandt a Look at Big-League Level?

Miami Marlins pitching prospect Karson Milbrandt has pitched well in the minors this season between Double-A Pensacola and Triple-A Jacksonville. His numbers were dominant at Pensacola, with a 4-1 record, a 1.34 ERA, and a 1.00 WHIP. His strikeout rate was also excellent at Double-A, with 70 strikeouts over 47 innings. His numbers have come back to earth a bit at Triple-A after his promotion, with a 4.15 ERA and 1.66 WHIP at Jacksonville. The dip in numbers is a bit concerning but is to be expected to some extent after just five Triple-A starts. Milbrandt, the No. 4 overall prospect for the Marlins, might have a path to the majors with Marlins starting pitcher Janson Junk currently on the 15-day IL. Should Milbrandt get a look to fill Junk's spot in the near future, he could prove to be a worthwhile pickup for fantasy managers in most leagues.
