2020 Fantasy Outlook
Yamamoto rode the rookie roller coaster in 2019. He began his big-league career by hurling 14.1 consecutive scoreless innings, registered an 8.13 ERA during a seven-game rough patch in July and August and capped the campaign with a one-hit, 10-strikeout performance over six innings in his final start of the season. Collectively, Yamamoto posted a 4.46 ERA (4.50 FIP) while notching a solid 25.2 K%, though he struggled with his control (11.1 BB%). He compensates for a middling fastball that sits at 91-92 mph with a kitchen-sink approach that includes six different offerings. Best among those is an excellent slider that ranked in the top 10% of the league in both vertical and horizontal movement, on which Yamamoto held batters to a .109 batting average. The 23-year-old has potential, but he'll need to show more consistency and fix his control issues in order to become a viable fantasy option. Read Past Outlooks

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 120 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

2019 Fantasy Outlook
Acquired by the Marlins in the Christian Yelich trade, Yamamoto was limited by injuries to just 13 starts. He recorded excellent numbers in those starts, finishing with a 1.83 ERA, 32.4 K% and 5.3 BB%. While three of those starts did come in a rehab stint at the rookie-league level, he was similarly effective at High-A Jupiter and Double-A Jacksonville. The 22-year-old's incredible numbers don't quite line up with his scouting reports, as his fastball sits in the high 80s, which may cap his ceiling as a back-end starter despite above-average command and a trio of interesting secondaries (curveball, slider and changeup). Those secondaries have fooled low-level hitters so far but may not be enough against more advanced hitters. Yamamoto has made just three starts at Double-A so far, but his addition to the 40-man roster in November could lead to his first callup at some point this season.
