Astros starting pitcher Jordan Lyles endured another rough outing as he lost back-to-back starts for the first time this season Saturday afternoon against the Angels.

Lyles (4-3) surrendered a two-run single to Alberto Callaspo and a two-run single to Erick Aybar in the fourth inning for his only damage of the day. The right-hander yielded four runs on five hits and two walks while striking out one over four innings in a 7-2 defeat.

Lyles has allowed 12 runs -- nine earned -- combined over his last two starts (nine innings), after starting the season 3-1 with a 3.48 ERA over his first nine starts. He is scheduled to make his next start Thursday at home against Tampa Bay.
