Mengden (1-4) allowed six runs on six hits and two walks while striking out six over 4.2 innings, but received no decision Friday at the Astros.
Mengden held the Astros scoreless the first time through the batting order, but followed that up by allowing two runs in the fourth inning and four more in the fifth inning, forcing his exit from the contest. After making four solid starts in June, he's now allowed 10 runs in his last 10 innings over two July starts to raise his ERA to 4.54. He'll make his next start after the All-Star break.
