Correia kicked off his season with solid starts against the Cubs and Cardinals, but he fell apart in the sixth inning of his last start against the Brewers, giving up a three-run bomb to Prince Fielder and allowing six runs total, four earned.
Wood, meanwhile, was brilliant in his season-opening start against the Brewers and reasonably strong in his last start in San Diego, but he allowed six runs in an April 8 start against the Diamondbacks. He doesn't have overpowering stuff and relies primarily on a fastball, cutter and change.
The Pirates lead the series 3-1 after breaking through for a bizarre win on Sunday. The Reds won in a blowout on Saturday, but Charlie Morton pitched a complete game on Friday to lead the Pirates to victory.
