There are a number of low ERA pitchers on the mound this Wednesday. The earliest game with two pits Matt Cain and the Giants against Tyler Chatwood and the Rockies. With their win Tuesday, a 2-1 game at Coors, the Rockies moved ahead of the Giants into second place in the NL West. Cain is back to his old form, pitching well but losing. His 2.88 ERA in four starts resulted in an 0-3 record as the Giants scored just seven runs in his games. Chatwood makes his third start of the season, having struck out 11 and walked one in 13 innings.

A few minutes later, Martin Perez leads the Rangers against Sonny Gray and the Athletics. Both youngsters own 3-0 records with similar ERAs, Perez at 1.86, Gray at 1.80. Neither has allowed a home run. A win by Texas moves the Rangers into first place in the AL West.

Michael Wacha faces Jonathon Niese as the Cardinals continue their series with the Mets. Wacha seems to be on his way to being a right-handed Cliff Lee, walking just three and strikeout out 25 in his first 26 innings this season. Niese stays out of trouble, with only 18 of his 74 batters faced having a runner in scoring position.

Tyson Ross and Kyle Lohse meet in Milwaukee as the Padres play the Brewers. Ross has some control issues, but makes up for his high walk rate with one home run allowed and 25 strikeouts in 25 1/3 innings. Lohse allowed just two home runs in 27 innings this season.

Finally, the only late game of the day features the 2014 debut of Cole Hamels as the Phillies face Zack Greinke and the Dodgers. This will be the third time Hamels pitched at Dodger Stadium, and the first time in five years. He allowed just two runs in 16 innings at the venue. Greinke allowed five home runs so far this season, but all of them were solo shots. He only allowed one other run this season.

Enjoy!
