Surkamp, 26, was once thought to be one of the rising stars in the Giants organization when he dazzled at Double-A Richmond in 2011. But in six starts with the Giants that season, Surkamp had a 5.74 ERA and a 1.838 WHIP in 26.2 innings with 13 strikeouts, posting a 2-2 record.
He missed all of 2012 after Tommy John surgery and made one start for the Giants last season, getting lit up for seven runs on nine hits in 2.2 innings against the Cincinnati Reds on July 23.
Surkamp was drafted by San Francisco in the sixth round in 2008 out of North Carolina State University.
Pill, 29, had fallen behind Brandon Belt on the depth chart at first base and with Buster Posey playing more frequently at first base, as well, and the addition of Morse to play left field, there was not going to be a lot of playing time available for Pill.
In 111 games and 259 plate appearances from 2011-13, Pill hit .233/.279/.404 with nine homers and 32 RBI. Last season, he had three homers and 12 RBI in 48 games and 92 plate appearances, hitting .224/.272/.376.
Pill was a seventh-round pick by the Giants in 2006 out of Cal State Fullerton.
