Detroit Tigers 2021 season starting pitchers grades.
Matthew Boyd: C+
An extremely strong start was brought to a screeching halt by injuries. When he first went down in mid-June, Matthew Boyd had a 3.44 ERA and was consistently throwing 5-7 innings per game. After the injury, he made two starts, gave up seven runs on 11 hits and four walks—a disappointing end to a strong half-season of work for a pitcher two years out from free agency.
Matt Manning: D+
It was painfully apparent that Matt Manning was overmatched in the MLB, but the Tigers were essentially out of options when they brought him up. Both his surface and underlying stats paint a miserable tale, where he was hit hard, lost control, and couldn’t strike hitters out. Is the potential still there? Most certainly, yes. Was this a rough year? For sure.
Casey Mize: A-
Now, this was the improvement we were looking for from the youngster. Casey Mize dropped his 2020 ERA from 6.99 to 3.71 en route to a strong showing in his first full major league season. He took a massive step forward and is really starting to look like that first overall pick the Tigers drafted only three years ago.
Wily Peralta: B+
Wily Peralta was a delightful surprise as an injury replacement. He made 18 starts and ate up 93 key innings throughout the middle of the season. He didn’t light the world on fire but well outperformed any expectations placed on him.
