"We wanted to go to 13 pitchers anyway," Phillies general manager Ruben Amaro Jr. said.
The Phillies had been short a man in the bullpen since they placed right-hander Luis Garcia on the 15-day disabled list on Friday with a strained forearm.
"We could have gone with some other guys," Amaro said. "He's got the experience, right now."
Right-hander Ken Giles remains on the minds of Phillies fans. He is 2-0 with a 1.12 ERA in six appearances since a promotion from Double-A Reading. He has allowed three hits, one run, five walks and has struck out five in eight innings.
"Giles is doing well," Amaro said. "He's still a guy that we'll continue to monitor. When he's ready, we'll bring him."
