Seattle will go for a series split after losing a close one 6-5 in 10 innings on Saturday night. Chase DeLauter performed his magic again with a two-run homer in the 10th inning for Cleveland after Seattle had tied it in the ninth. The Mariners will start Emerson Hancock and he has a .160 opponent batting average against the Guardians in 25 at-bats with no extra-base hits. Slade Cecconi is 0-1 with a 1.50 ERA in one start against the Mariners and he finished spring training with a 1.62 ERA in 16 2/3 innings. However, Cecconi gave up 34 runs (31 earned) in 55 2/3 innings the last two months of the 2025 season. Take the Mariners and the UNDER.

Cleveland at Seattle
March 28, 2026
9:40 PM Eastern
The Seattle Mariners seem to be stamped as the AL team that can make it to the World Series. Maybe the depth of their lineup is questionable, but the pitching certainly looks good. The Mariners split two games with Cleveland and look to take the rubber game tonight in Seattle. Bryan Woo gets the ball for the Mariners, and he seemed to get better with each start last season. The Mariners won seven of their last eight starts and went 7-4 to the UNDER in their last 11. Joey Cantillo pitched a lot of low-scoring games last season. He was 13-8 to the UNDER in his last 21 starts. I think the runs will be in short supply in this game. Make the play UNDER the total.
