Round Four, Match One
Collin McHugh, RHP
Not since Hunter Pence's hot first season have the Astros had such a legitimate Rookie of the Year candidate. McHugh absolutely came out of nowhere and made the Astros coaches and brass look very, very smart, posting a 2.73 ERA and a 3.83 K/BB ratio in 154.2 innings of work. Brent Strom's pitch tunneling focus seemed to do the trick, and all signs point to McHugh being at least a solid #3 starter going forward. With almost all of his club control remaining, the Astros appear to have scored one of the biggest waiver coups in recent history. -- Brian Stevenson
Dallas Keuchel, LHP
Keuchel made some people look really smart and a few people pretty silly last season. Non-players that is; he made basically all the other players he faced look silly. Breaking out and turning in an ace-like season, Keuchel led the Majors in ground ball rate at 63.5% and finished with exactly 200 innings of work in the book. Though he might regress a tad, nearly everything about 2014 looked legitimate, and he'll form a really nice 1-2 punch with fellow breakout Collin McHugh if all goes as planned. -- Brian Stevenson
