PHOENIX (AP) -- Arizona Diamondbacks ace Madison Bumgarner has been placed on the 10-day injured list with a mid-back strain.
The left-hander was lifted after two innings Sunday against San Diego due to back spasms.
The Diamondbacks placed Bumgarner on the injured list Monday and selected the contract of right-hander Jeremy Beasley from their alternate training site.
Bumgarner allowed six runs on five hits in two innings against the Padres to remain winless since signing an $85 million, five-year deal with Arizona last offseason. The four-time All-Star has seen his velocity dip into the upper 80s this season and has a 9.35 ERA after Sunday's start.
Bumgarner was a four-time All-Star and three-time World Series champion in 11 seasons with San Francisco.
Beasley will be making his major league debut.
