The 34-year-old Oswalt had two stints on the disabled list last season because of lower back inflammation. He went 9-10 with a 3.69 ERA in 23 starts for the Phillies. His 139 innings pitched were his lowest total since 2003.
Los Angeles Angels ace Jered Weaver has been placed on the 15-day disabled list with a lower-back injury that likely will force last season's AL Cy Young runner-up to miss at least two starts. Weaver threw just 12 pitches Monday night against the Yankees before pulling up awkwardly after a pitch to Robinson Cano.

The Tigers were in New York to play the Yankees.
