Luis Castillo

Regression just never really hit for Castillo last year, despite a walk rate of 10.1%, fourth-worst in the league among qualified pitchers. There's no doubting Castillo's stuff, particularly his devastating changeup, and the Reds should be more competitive than they have been in years. But he simply has to cut down on the free passes if he wants to build on his breakout 2019. There's every reason to think he will as he continue to grow as a pitcher, and should make a reliable second fantasy starter.

Luis Castillo allows five runs in final start of season

Luis Castillo (15-8) took the loss Thursday against the Brewers, allowing five runs on five hits and four walks across five innings. He struck out eight.

Fantasy Impact

Castillo ends his breakout 2019 on a less-than-impressive note, struggling to find the zone and allowing five runs in as many innings. Castillo struggled with walks for a portion of the season, but seemed to correct that issue over time. He demonstrated elite strikeout potential, and a devastating changeup. He finishes the year with a 3.40 ERA and 226 strikeouts in 190.2 innings pitched. He'll enter 2020 as the Reds' ace, and an elite fantasy pitcher.
