Flexen didn't factor into the decision in Sunday's 10-4 extra-innings win over Arizona, allowing three runs on four hits and two walks with four strikeouts in six innings.
Flexen was rolling through five innings but permitted three runs on three hits in the sixth to fall behind 3-2. Seattle eventually knotted the score and went on to win in extras while Flexen posted his fourth quality start in five turns. The 27-year-old has now allowed no more than three runs in any of his last seven starts and has a 2.93 ERA in the span.
