The trade for Musgrove is pending medical reviews, per sources, and will be sending a large package of prospects back to the Pirates. Hudson Head, a well-regarded center fielder, is expected to be among the group heading to Pittsburgh.
Musgrove, 28, was 1-5 with a 3.86 ERA in eight starts for the Pirates in the coronavirus pandemic-shortened 2020 season.
Musgrove, the team’s Opening Day starter in 2020, is set to make $4.45 million in 2021 after he and the Pirates agreed to a contract last Friday to avoid arbitration.
He is 29-38 with a 4.33 ERA over 108 appearances in five major league seasons, including 83 starts.
Musgrove is the third starting pitcher acquired via trade by the Padres this offseason. San Diego acquired left-hander Blake Snell and right-hander Yu Darvish in separate blockbuster trades last month with the Tampa Bay Rays and Chicago Cubs, respectively.
