With the likely departure of right-hander Jake Arrieta in free agency, the Philadelphia Phillies will have an open spot in their starting rotation ahead of the 2021 season.
Starting pitching was a major strength for the team this past season as Phillies starters posted 6.9 fWAR, the third-best mark in the majors. The team will retain four of its main starters from 2020 in Aaron Nola, Zack Wheeler, Zach Eflin and Spencer Howard, but will need to find a reliable fifth starter in order to replicate the same success.
The Phillies may very well look to the free-agent market to bolster the starting rotation.
