Estes (6-7) allowed four runs on six hits and struck out three without walking a batter over four innings, taking the loss Thursday versus the Mariners.
Estes coughed up a pair of homers to Cal Raleigh and Julio Rodriguez, making it the fifth time this season he's allowed multiple long balls in a start. Estes has now given up at least one home run in seven straight starts, but he has pitched well over that span. Thursday's start ended an impressive run of nine straight outings in which he didn't allow more than three runs. The 22-year-old has a 4.46 ERA through 111 innings in his rookie campaign.
