As a result of a somewhat disappointing 2016 that began with World Series aspirations and ended with a third-place finish in the AL West, the Astros have been aggressive in upgrading their roster this offseason. Since November, Houston has either traded for or signed Brian McCann, Josh Reddick, Carlos Beltran, Nori Aoki and Charlie Morton in an attempt to beef up a roster that won 84 games last season. You’ll notice that only one of those five – Morton – is a starting pitcher, and he’s a back-end type who has dealt with a laundry list of injuries during his career.
