21-year old lefty starting pitcher Madison Bumgarner has really stepped up for the Giants as of late.  In his last 7 starts, Bumgarner is 4-2 with a 2.28 ERA and a 1.07 WHIP.  He has now pitched in 29 games (all starts) for the Giants so far this year and he is 10-12 with a 3.37 ERA and a 1.23 WHIP.  He has given up 182 hits in 181 2/3 innings so far this year, but he has limited the damage by whiffing 170 batters and walking only 42.  Bumgarner will be the Giants’ #3 starter going forward behind Tim Lincecum and Matt Cain.
