Mitch Keller starting Sunday for Pirates

Pittsburgh Pirates pitcher Mitch Keller will start Sunday's series finale against the St. Louis Cardinals.

What It Means:

Keller will follow Joe Musgrove and Trevor Williams in the Pirates' opening rotation. The 24-year-old right-hander struggled to a 7.13 ERA last season over his first 11 starts in the majors.

numberFire's models expect Keller to record a 4.15 ERA and 1.34 WHIP with 56 strikeouts and 17 walks over 52 innings this season.
