"Obviously Seager hitting behind Robbie with a righty on the mound makes sense," McClendon said. "LoMo is swinging the bat well. And it takes a little of the pressure off Corey as well out of that four-spot against a right-hander. Hopefully we can get him to relax a little more down there and maybe get a few more pitches to hit."
The Mariners are 13-8 with Seager hitting fourth, 3-1 with Morrison there and 17-17 with Hart.
"Seager did a great job hitting there," McClendon said. "So did LoMo. So I like those three guys lining up against the righty."
