San Francisco Giants Player News: Pitchers

News: Lopez was designated for assignment by the Giants on Sunday, Maria I. Guardado of MLB.com reports.
Impact: Lopez was claimed off waivers by the Giants in February but will return to the waiver wire as the team needed space on the 40-man roster for the acquisition of veteran catcher Erik Kratz. The 25-year-old posted a 4.47 ERA, 1.30 WHIP and 117:41 K:BB across 141 innings (26 starts) at Triple-A last season.
