Both teams come into this series struggling but the Mariners are the more talented of the two teams. The A's have the 5th worst ERA in baseball and their bullpen is bad. Kirby has been effective this season with quality starts in half of his outings this season. While not outstanding, Kirby should have more confidence turning the game over to his bullpen. Seattle's bullpen isn't stellar but battling an offense that is hitting under .200 at home. Seattle's offense, fresh off of a four HR outburst last night, is the offense to go with in this one.
