2025 Fantasy Outlook

Johnston has been toiling in the Marlins organization since 2019. He spent last season with Triple-A Jacksonville, posting a 99 wRC+. His main asset is an above average contact rate, but he doesn't hit the ball hard. Johnston will turn 28 years old in June, and at 5-11, 205 pounds, more power is possible but not likely. He's exhibited the power/speed combination envied by fantasy managers, but it's unclear how his quantity and quality of contact will translate to the highest level, especially as a first baseman. The Marlins lack a proven commodity at the position, so a hot spring could propel Johnston into the mix. At best Johnston is worth tracking in the spring. Read Past Outlooks

Johnston went 2-for-4 with a walk, two home runs and three RBI in Saturday's 6-4 extra-innings win over the Tigers.

Analysis
After taking Troy Melton deep for a solo shot in the sixth inning, Johnston walked it off in the 11th with a two-run homer off Rafael Montero. The 28-year-old rookie came into the game with just one long ball in his first 32 big-league contests, and the performance may have snapped a September swoon for Johnston in which he'd gone just 2-for-21 (.095) with zero RBI over his prior nine games.
