At 10:10 ET, my AL West GOY is on the Seattle Mariners. Behind another big effort from their young star pitcher Garret Crochet, Chicago beat the Mariners in extra innings yesterday. The Rangers got a great game from their starter Lorenzen and defeated the Dodgers. Nice win for the defending champions but the pitching matchup for tonight's series opener in Seattle is strongly in favor of the Mariners.

As a starter, Heaney is 1-7 with a 4.22 ERA and 1.273 WHIP. His WHIP is 1.396 on the road. Does he deserve to have a better record? Perhaps. But he's not as deserving as Castillo! Castillo is 5-7 with a 3.35 ERA and 1.16 WHIP. AT home, he has a 2.95 ERA and 1.125 WHIP. One important difference between Castillo and Heaney is that Castillo averages greater than 6 innings per home start. Heaney averages less than 5 innings per road start. Ranger relievers have stunk on the road all season. Seattle relievers have been strong at home. After dropping yesterday's game, the Mariners are 13-8 against left-handed starters. One of those 13 wins was a result of a game in April when Castillo and Heaney faced each other at Texas. This will be another victory for Castillo's team. Play on SEATTLE
