The San Francisco Giants received a boost in their fight for a National League wild-card playoff spot when the team activated right-handed reliever John Brebbia from the 60-day injured list.
In a corresponding move, the team released veteran outfielder AJ Pollock.
Brebbia, 33, has appeared in 29 games (eighth starts) this season for the Giants, going 2-0 with a 3.14 ERA. He has 36 strikeouts in 28 2/3 innings.
Brebbia has a 14-10 mark and a 3.32 ERA over six seasons -- three with the St. Louis Cardinals and three with the Giants.
Pollock, 35, hit just .165 in 54 games (49 with the Seattle Mariners this season.
He had been on the 10-day injured list with a strained oblique.
The Giants also optioned right-hander Tristan Beck to Triple-A Sacramento. The 27-year-old made his major league debut in April and was 3-3 with a 4.04 ERA in 31 games (two starts).
