The Padres will call up Robbie Erlin from Triple-A Tucson to start against the Phillies on Wednesday.
"We like we saw when he beat the Blue Jays. He's getting to a point where he's about to break through," Bud Black said.
Erlin spot-started for San Diego earlier this month and allowed just two runs over six-plus innings, getting the win against Toronto. He has pitched in relief twice for the Padres in 2013.
The 22-year-old left-hander was a third-round pick of the Rangers in 2009.
