The Astros have some momentum winning two in a row to keep their season alive down 3-2 in the best-of-seven ALCS. 
Only twice all season has Tampa Bay lost more than two in a row. I don't see the Rays losing a third consecutive game. Tampa Bay has the more established starting pitcher, superior bullpen and better manager. 
Blake Snell won the AL Cy Young Award three seasons ago. He's been strong this season and during the playoffs. Snell defeated Houston five days ago holding the Astros to one run in five innings. 
The Astros are going with Framber Valdez, who has posted solid numbers but has control issues and gives up the long ball. Valdez has issued seven walks in his 18 innings of postseason work and has surrendered three homers during his last two starts.
