Cardinals starter Michael Wacha took a step back from his solid debut as he was roughed up in a no-decision Tuesday against the Diamondbacks.

Wacha surrendered a run-scoring single to opposing starter Tyler Skaggs in the second and a three-run home run to A.J. Pollock in the fourth. The right-hander also allowed two runs in the fifth and was charged with six runs on 10 hits and a walk while striking out four in 4 2/3 innings.

Wacha's ERA ballooned to 5.40 after his second big-league start. He will make his next start June 11 against the Mets at Citi Field.
