Arizona at Pittsburgh

Would anyone have taken a wager that a week into August the Pittsburgh Pirates would have just one less win than the NY Yankees? Thus is the case, as Pittsburgh has blossomed after two decades of humility. Speaking of the Yankees, former Yankees farmhand Jeff Karstens has won three straight starts for the Pirates, and five of his last six. Those six games have seen the Pirates win by an average of over 2 runs per game. The Pirates are 34-16 at home for a reason, as their last nine here have seen opponents score just 16 total runs or 1.8 per contest, and the D-Backs didn't produce any here last night. Play Pittsburgh on the runline.
