Especially if they want to overpay for relievers. Many teams are abandoning this because of the high volatility of relief pitching. It's still hard to say if the Astros will keep this up.. their starting pitching, despite Keuchel and McHugh, has issues. Their 3-5 starters(Hernandez, Feldman, and a grab bag of Peacock/Asher/Deduno) have been awful. And of course, the Angels are still a threat in their division. Of course, they're also winning because the AL West is utter trash.
LAA- can't hit, but are decent enough pitching wise (5th in the AL in ERA)
SEA- SP not really too bad, but that bullpen.. yuck! And they don't hit much outside of Nelson Cruz, with Cano and Seager both down compared to 2014.
TEX- Surprsingly, the SP hasn't been too much of a problem outside of Detwiler. Weak bullpen, and loads of offensive struggles, of which Odor was just sent down. Hamilton is on the way, though..
OAK- Hit very well, but that pitching (both starting and bullpen), along with terrible defense, are killing the team.
Houston's basically the best team in a very bad division.
