Venditte was traded to the Phillies on Sunday in exchange for outfielder Joey Curletta.
The 31-year-old spent time with the Blue Jays and Mariners last season but found relatively little success with either organization at the major league level. However, the Phillies lack bullpen depth, and given his niche as a switch-pitcher, Venditte could push for a spot with the big league bullpen if he can piece together a few good spring appearances.
