FanHouse:
Astros - 20th
"The Astros are 8-2 after their 0-8 start. Sure, three of those wins came against the scuffling Pirates, but with Lance Berkman back in the lineup the 'Stros are on an undeniable tear. They don't play a team that's currently over .500 until the Padres at the end of next week, so there's no reason to think it can't continue for a least a bit longer."
Sporting News:
Astros - 21st
Houston roared out of last place in this poll by winning seven of eight, against the Cubs, Marlins and Pirates. Lance Berkman's return to the lineup has helped.
