Ehire Adrianza is expected to receive most of the playing time at second base while Panik heals. Gregor Blanco, who has started 52 games this year, will receive more activity as Pagan mends. That could be a complicated process, since Pagan's left knee also is inflamed.
The Giants filled Panik's spot on the 25-man roster by purchasing the contract of infielder Kelby Tomlinson from Triple-A Sacramento. A non-roster invitee to Spring Training this year, Tomlinson hit .321 while dividing this season between Triple-A and Double-A Richmond.
Panik's condition wasn't improving, though the 2015 National League All-Star sat out three of the Giants' previous five games.
