To begin the year, the pitching staff for the Arizona Diamondbacks was absolutely terrible. Through most of the beginning of the season, the rotation was on pace to have arguably the worst year in the history of baseball. Their ERA was nearly a point higher than the highest rotational ERA in single-season history.
In the month of May however, that has all changed. The Diamondbacks have an ERA of 3.45 in nine games, and that in turn has led them to a 6-3 record. Much of the success can be attributed to Bronson Arroyo, who has yet to give up an earned run this month, as well as Josh Collmenter, who has an ERA of 1.59 in his only start in May.
Chase Anderson, who made his major league debut in replacement of Mike Bolsinger, went 5.1 innings, giving up just two hits and a run to pick up a win over the Chicago White Sox. If he can continue to pitch anywhere near the level that he did in his debut, Anderson would give the pitching staff a huge boost as well as fill a large hole in the back end of the rotation.
With such a promising start to the month, we are finally seeing how the Diamondbacks should perform given the talent that they have in their organization.
