Scouting Report
Marlins Video
Drafted by the Marlins in 2020 (second round, $2.4M signing bonus)
August 2026 update: Fulton has had three brief stints on the Marlins active roster this season, totaling 14 innings pitched with a 4.50 ERA and 3.52 FIP.
The left-hander's signature sweeper is difficult to square up. That is his most-used pitch, followed by his four-seamer, slider, sinker and changeup.
Control continues to be a glaring issue as he's thrown only 56.1% of his pitches for strikes in the majors.
Fulton will enter 2027 with one minor league option left.
