The Giants have designated righty reliever Vinnie Chulk for assignment. Chulk has pitched in 27 games (0 starts) for the Giants this season and he was 0-3 with a 4.83 ERA and a 1.29 WHIP. The Giants have recalled 25-year old righty reliever Sergio Romo to replace Chulk in the bullpen. Romo has pitched in 24 games in AA ball this season and he is 1-3 with 11 saves, a 4.00 ERA and a 1.07 WHIP. Romo has whiffed 30 batters in 27 innings so it appears that he has good stuff.
