Seattle at Boston

Seattle is 15-4 on the runline, including 7-1 on the road this season, and the Mariners currently are tied for the AL West lead with a 12-7 record after beating the Red Sox 7-3 on Thursday. Mitch Haniger hit a three-run homer in the 10th inning after Sam Haggerty hit a go-ahead double, and Seattle somehow won the game while totaling only three hits. Boston has cooled off considerably, losing four of its past six games, and will face Yusei Kikuchi, who gave up two runs in six innings against the Twins in his only road start this year. Martin Perez has allowed seven runs on 12 hits in 8 2/3 innings in two home starts for the Red Sox. Perez didn't make it through the fourth inning on Sunday when he allowed four runs on seven hits in 3 2/3 innings against the White Sox. Take the Mariners on the runline.
