Drew Smyly started for the Rays and allowed two runs in 6 2/3 innings to get a no-decision. He struck out a career-high 12 batters. Nathan Karns started for the Mariners, making his first start against his former team, allowing two runs in five-plus innings to also earn a no-decision.
MOMENTS THAT MATTERED
