Jorge De la Rosa is 4-0 with a 2.92 ERA so far in 2011
Colorado's pitching has been quite a story through the first month of the season.
While ace Ubaldo Jimenez hasn't been anything close to what he was last season (currently 0-2 with a 7.20 ERA), the rest of the staff has done well for Colorado.
Jhoulys Chacin, the young right-hander who pitched his first full season for the Rockies last year, is 4-2 with a 2.85 ERA so far in 2011. He has struck out 32 while walking 13.
Jorge De La Rosa, the veteran lefty, had a spectacular April, and is currently 4-0 with a 2.92 ERA. He's struck out 37 while walking just 12. So far he's only had two starts in which he didn't pitch at least six innings, and opposing hitters are batting just .197 against him.
With Jimenez, Chacin and De La Rosa slated for this weekend, the Giants will have their hands full.
But let's not forget the staff on the other side.
Matt Cain, Madison Bumgarner and Ryan Vogelsong will take the hill for San Francisco.
Cain is coming off a solid outing against Washington on Sunday, giving up just two runs on seven hits over six innings and getting a no-decision.
Young left-hander Madison Bumgarner will get the ball on Saturday. Bumgarner struggled out of the gate this year, but had a good start on Monday against the Nationals, in which he went seven innings, yielding no earned runs on just four hits, striking out seven and walking just one. Madison looks to build on that solid performance with an encore against the Rockies.
Ryan Vogelsong had a fantastic return to a starting role when he defeated his old team, the Pittsburgh Pirates, in his first start in seven years on April 28, going 5.2 innings while allowing two runs on four hits and tying a career-high with eight strikeouts. He had a rough outing against the Mets on May 3 but is looking to rebound against the Rockies Sunday.
