Verlander is 5-1 with a 2.24 ERA against Seattle this season in six starts. Gilbert is 2-1 with a 2.52 ERA against Houston in four starts. Both pitchers are comfortable facing these lineups and are backed by sturdy bullpens. This feels like a one-run game decided late. Mariners are 5-0-1 to the under to open a series in their last six. Runs will be at a premium in this one. Take the under.
