McHugh's 2017 campaign got off to an ominous start as an early-spring dead arm turned into a right elbow impingement, delaying his debut until July 22. He started 12 contests, providing a timely shot in the arm to the Astros over the second half. McHugh's numbers were an improvement over his disappointing 2016, in part due to allowing only seven homers in 63.1 innings. He also significantly improved versus right-handed batters (.694 OPS against in 2017 versus .777 in 2016), incorporating a slider to complement the cutter he throws versus lefties. McHugh's career 22 percent strikeout rate and seven percent walk rate are both better than league average, portending success if he can continue minimizing homers. McHugh will contend for a spot in a crowded Astros rotation, but the acquisition of Gerrit Cole probably means he'll start the season working out of the bullpen like he did during the 2017 postseason. Unless his role is clarified in the spring, don't pay for more than 125-130 innings.

Those who bought in on McHugh in 2016 were left mostly disappointed as he turned in damaging ratios along with modest totals in wins and strikeouts. However, it was not a disastrous season by any means, and he in fact improved in several areas, most notably with his strikeout rate (22.2 percent) -- a rebound supported by his third straight season with a swinging-strike rate north of 10 percent. Unfortunately, a pair of disastrous outings (13 combined earned runs over the span of two innings) marred his overall numbers. He threw roughly 20 fewer innings than he did in 2015 despite making one additional start as manager A.J. Hinch was quick to give him the hook on his off nights. Home runs were a problem (25 allowed), but an improvement there in 2017 could return McHugh to mixed-league prominence. While there is some uncertainty at the back of the Houston rotation, McHugh should be secure in his role entering spring training.

After a 2014 breakout that put him in the AL Rookie of the Year conversation, McHugh entered last season with an assured rotation spot with the Astros. The 28-year-old picked up right where he left off, going 3-0 with a 2.92 ERA in April before suffering his first loss of the season on May 12. McHugh wasn't at his best from May through July, but a strong August (1.89 ERA) and four wins in September attributed to solid numbers overall, as he finished 19-7 with a 3.89 ERA, 1.28 WHIP and 171:53 K:BB ratio over 203.2 innings. While his 19 wins were tied for third-best in the majors, his strikeout rate (7.6 K/9) dipped slightly, but that may be attributed to less use of his curveball and slider. The right-hander will open 2016 in the upper half of Houston's rotation after earning his first postseason victory with a win over the Royals in Game 1 of the ALDS.

McHugh opened 2014 in the minors after a disastrous spring (14.29 ERA), but he received a quick call from Houston when Scott Feldman's injury opened up a spot in the rotation. Once he arrived, he never looked back, going 11-9 with a 2.73 ERA, 1.02 WHIP and 157:41 K:BB in 154.2 innings (25 starts). His curveball and slider were particularly effective, attributing to a career-best 9.1 K/9 ratio. McHugh's impressive season put him in the AL Rookie of the Year conversation, and while he didn't win the award, he definitely assured himself a spot in the Astros' starting rotation to open 2015.

The fifth spot in the Rockies' rotation was a continual trouble spot throughout the second half of the season, and McHugh was arguably the worst of those who filled the role, going 0-3 with a 9.95 ERA in his three starts. Despite his quality minor league numbers, McHugh has been abysmal over his 47 innings in the big leagues, with his strikeout rate bottoming out and an inability to avoid the long ball proving to be his biggest pitfalls. McHugh will compete for an Opening Day roster spot, in a role to be determined, with the Astros during spring training after being claimed off waivers in December.

McHugh held his own after a promotion to Triple-A Buffalo last season, carrying a 70:29 K:BB and finding a way to retire hitters without an overpowering arsenal. After throwing 129 innings between two levels in 2011, McHugh was likely out of gas by the time he broke through to the big leagues, having already logged 148.1 innings over 25 starts between Binghamton and Buffalo. If there are any openings in the rotation when the season begins, McHugh figures to be in the mix to handle a temporary spot as the team's fifth starter, but he will have to fend off Jeremy Hefner and youngsters Jenrry Mejia, Jeurys Familia and Zack Wheeler to keep that spot.
