Troy Johnston

28-Year-Old First Baseman1B
Miami Marlins
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
Signed a one-year contract with the Marlins in July of 2025.
Idle against southpaw
1BMiami Marlins
September 1, 2025
Johnston is out of the lineup for Monday's game against the Nationals.
Analysis
The Nationals are sending lefty Andrew Alvarez to the hill for the series opener, so Johnston will head to the bench along with another lefty-hitting lineup regular in Liam Hicks. Johnston closed August with a .293/.328/.414 slash line, one home run, one stolen base, seven RBI and five runs over 23 games.
