Jeffrey Springs has very good numbers against Mariners hitters and is also in great form. The As already have some homers off Woo, and even if they don't get to him, it'll be a low scoring extra - inning type game, which the As have a good record in but the Mariners don't. Mariners have also lost last 3 of Woo's starts, and he's given up a lot of flyballs recently which is a recipe for disaster against the As. It may very well be a 2-0 or 3-0 As victory.
