Right-hander Francisco Cordero has been put on the 15-day disabled list by the Houston Astros because of an inflamed right big toe.
Manager Brad Mills says he first learned of Cordero's injury on July 25, five days after the reliever was acquired from Toronto.
Cordero is 0-3 with a 19.80 ERA and three blown saves in six games with Houston. Mills says Wilton Lopez has assumed the closer's role.
Overall this season, the 37-year-old Cordero has a 7.55 ERA and has two saves in eight chances. He is second to Mariano Rivera among active players with 329 saves.
Right-hander Mickey Storey was recalled from Triple-A Oklahoma City, where he was 7-4 with a 3.05 ERA. Storey was with the team for Friday night's game against the Braves.
