Things are looking down for Ryan Dempster.

Make the Cubs’ Ryan Dempster 0 for April, 0 for May, and 0 for 2012 thus far.

The snake-bitten Dempster hasn’t won since last August. He was victimized by Kerry Wood’s struggles on opening day and a couple of early-season meltdowns by closer Carlos Marmol. He also drew precious little run support from the Cubs’ hitters. It wasn’t until May that they scored even three runs in a game he started. He entered today’s game at Wrigley Field 0-3, but fourth in the National League in earned run average at 2.14. According to the Elias Sports Bureau, that’s the lowest for any pitcher winless over his first eight starts of the season since ERA became an official statistic in 1912.
