Velasquez won a rotation spot with a strong spring training and made a major impression in his second regular season start, striking out 16 in a complete game win over the Padres. In early June he went on the disabled list with a strained right biceps that initially looked like a serious issue, but ultimately only caused him to miss a few weeks of the season. He was shut down in early September, having thrown a career-high 136 innings between a rehab start and his starts in the majors. Velasquez throws a mid-90s fastball that tops out around 98 mph, which he complements with a curveball, changeup and slider. His 11.2 percent swinging strike rate ranks him among the better strikeout pitchers in baseball and gives him the potential to be a major fantasy asset. He does have some work to do on reducing the free passes, and he needs to utilize his defense a bit more to help keep his pitch count down and to get deeper into his starts.

Velasquez logged just 77 innings between the minors and Arizona Fall League in 2014 so he was limited to a swingman role in 2015 (27 appearances, 12 starts). A lat injury from that Fall League appearance pushed his season debut to early May and so he only logged 88 innings, meaning we still might not see a full starter's workload from the 24-year-old. However, a popular adage from the great Ron Shandler rings true with Velasquez: "Draft skills, not roles". Velasquez has the kind of talent that can make teams forget whatever "plan" they had and just use the best guy available once ready. Walks are the key issue, but his 62 percent first-pitch strike rate was actually a tick above average and will help him chisel into that 3.4 BB/9 if it holds. He's not a finished product, but two swing-and-miss pitches and a developing changeup that was given 60-grade upside when he was coming up make him very appealing. Further, he has a chance to earn a spot in the Phillies' rotation to start the year after coming over in the Ken Giles trade.

Velasquez has a long history of injuries that includes Tommy John surgery in 2010, so it was no big surprise when a groin injury cost him two months last season. When healthy, however, the 22-year-old right-hander is a standout pitcher in the Astros' system. He's moved along slowly thus far (in large part due to the injuries), but his first taste of Double-A appears likely this season after a strong 2014 pitching with the Gulf Coast League Astros and High-A Lancaster. Between the two affiliates, Velasquez went 7-5 with a 3.52 ERA and a remarkable 12.8 K/9 in 64 innings. With a low-90's fastball, plus changeup and improving curveball, he has mid-rotation potential in the big leagues if he can string together a few seasons of full health in the upper levels of the minors. His recent addition to the Astros' 40-man roster indicates he may be closer to the majors than we think.

Three years removed from Tommy John surgery, Velasquez turned in a fine season pitching between Low-A Quad Cities (25 games, 16 starts) and High-A Lancaster (three starts). The 21-year-old right-hander posted excellent ratios (10.3 K/9, 0.6 HR/9) to go along with a 9-6 record, 3.54 ERA and 1.16 WHIP over 124.2 innings. Velasquez appears likely to progress to Double-A, where he will look to improve his command (3.0 BB/9) and the quality of his offerings -- a low-90s fastball, curve and changeup.
