Houck's first meltdown start occurred on April 14, when he gave up 12 runs (11 earned) over the span of 2 ⅓ innings against the Tampa Bay Rays. It was the worst outing by a Red Sox pitcher in more than 60 years. He nearly topped that Monday.

Tanner Houck has an 8.04 ERA through nine starts this year, and with rotation decisions looming, the Red Sox might need to pivot.

Monday marked the second time this season that Houck allowed 11 earned runs over 2⅓ innings. Those are the two worst starts in franchise history.
