PHILADELPHIA -- The Phillies acquired some bullpen depth Sunday when they claimed left-hander Ken Roberts off waivers from the Rockies.
Roberts has been optioned to Triple-A Lehigh Valley, but he could join the Phillies on Tuesday when rosters expand. The Phillies are thin on left-handed relievers. They traded Jake Diekman to Texas in July. They designated Cesar Jimenez for assignment recently, and the Brewers claimed him off waivers. Then last week Elvis Araujo strained his left groin and landed on the disabled list.
