The Chicago Cubs have added reliever Jesse Chavez to their roster and placed right-hander Anthony Bass on the 10-day disabled list with a back injury.
Chavez was acquired in a trade with Texas on Thursday for minor league pitcher Tyler Thomas. The 34-year-old Chavez went 3-1 with a 3.51 ERA in 30 appearances with the Rangers this season.
The Cubs also recalled reliever Dillon Maples from Triple-A Iowa and optioned right-hander James Norwood to their top farm club. Reliever Luke Farrell was brought up from Iowa.
Bass has a strain on the right side of his back. He was just activated from the DL on Thursday after being sidelined by an illness.
