Mengden (1-4) allowed four runs on seven hits and four walks while striking out five over 5.1 innings to take the loss Sunday against the Pirates.
After holding the Pirates scoreless through four innings, Mengden fell apart and gave up all four of his runs in the fifth and sixth innings, leading to his fourth loss of the year. This was the first time in five starts that he's allowed more than three earned runs in a game, and he has a 3.48 ERA on the season. He'll make his next start Friday at the Astros.
