Gibson (7-4) gave up six runs on seven hits and five walks while striking out three through 4.1 innings, taking the loss against the Red Sox on Wednesday.
Gibson struggled mightily with his command, walking five batters and enduring a 38-pitch second inning. He threw only 49 strikes in his 94 pitches overall, and he now has a 7-4 record with a 4.18 ERA through 14 starts this season. Gibson will look to get back on track in his next start Tuesday against the Rays at Target Field.
