Thornton allowed four runs (three earned) on nine hits and a walk over four-plus innings Friday, striking out four and taking a no-decision in a 7-4 loss to the Mariners.
The right-hander was twice spotted leads, but he couldn't make either of them hold up. He was pulled in the fifth inning in favor of reliever Buddy Boshers after allowing a J.P. Crawford solo home run and a single to Austin Nola. Thornton has a 5.34 ERA and 1.52 WHIP with 117 strikeouts over 124.2 innings this season. The 25-year-old is expected to make his next start versus the Braves on Wednesday.
