The Giants have placed Vinnie Chulk on the 15-day disabled list with a blood clot in his right arm. He is likey done for the season which is a shame because he pitched pretty well this season for the Giants. He pitched in 57 games this season for the Giants and he was 5-4 with a 3.57 ERA and a 1.26 WHIP. The Giants have recalled Tyler Walker to replace Chulk in the bullpen. Walker has pitched in 150 major league games in his career and he is 13-9 with 34 saves, a 4.77 ERA and a 1.50 WHIP.
