Red Sox SP Martin Perez:
He is another new face in the Red Sox rotation. As Porcello has gone elsewhere, the Red Sox decided to sign Martin Perez in December of 2019.
In his first eight seasons in the majors (7 with the Rangers and 1 with the Twins), Perez has had 4+ 10-win seasons. He has a combined 4.72 ERA in his career thus far.
He will most likely serve as the No. 3 starter once Rodriguez becomes available. As of right now, however, he might even be labeled the 2nd starter in the rotation to start the season. This gives him a better chance to earn the start on Opening Day in comparison to Weber.
During Spring Training 1.0, he made three starts, going 0-1 with a 1.35 ERA. He gave up 1 earned run in 6.2 innings pitched.
It would help Boston to a great extent if he exceeds expectations out of the rotation. The Red Sox are going to need their starters to step up with Sale, Price, and Porcello all not pitching for them in 2020. With not many notable and familiar players coming out of rotation for the Red Sox this season, Perez has an alright chance of making the start on Opening Day.
Percent chance: 10%
