This from Kiley before Blair had a nice year at AAA.
3. Aaron Blair, RHP
Current Level/Age: AA/22.2, 6’5/230, R/R
Drafted: 36th overall (sandwich round) in 2013 out of Marshall by ARZ for $1.435 million bonus
Fastball: 50/55, Curveball: 45/50+, Changeup: 50/55, Command: 45/50
Scouting Report: Blair has slowly improved since being drafted last June that some in the organization have him as the #1 prospect in the system. He isn’t as flashy as Bradley and Shipley, but Blair has three pitches that all have been plus at times for scouts and are all regularly above average. One scout compared Blair’s ability to get heavy life on pitches to Roy Halladay, in part due to how big Blair’s hands are.
Another scout compared him as an overall pitcher to John Lackey and Lance Lynn, as a big and unspectacular but steady #3/4 starter that outperforms many more heralded talents. As noted in Bradley’s report, some think Blair may jump past the incredibly talented Bradley to settle in a big league rotation spot first amongst this top group of three Arizona prospects.
Blair sits 90-94 and has been up to 96 mph this year, with scouts noting the arm speed got a notch better this season, helping all of his stuff play up. He’s a control over command guy that throws a lot of strikes and the heavy life on his fastball helps induce weak contact rather than an excessive amount of strikeouts. Blair’s curveball was the concern as an amateur and early in his pro career, but now consistently shows average with some grading it as high as plus at times. His changeup has been his go-to off-speed pitch for years at is also consistently above average.
Summation: As you can see in the projected path, I think Blair starts the year in AA, gets a taste of the big leagues and sticks. He’s the kind of guy that these sorts of lists consistently underrate and then he never gets re-ranked when he proves us wrong as a big league asset. Consider this an advance apology for ranking him 3rd. Sorry, Aaron, but you need people like me that don’t learn from history and tell you that you aren’t good enough.
FV/Role/Risk: 55, #3/4 starter, Low (2 on 1-5 scale)
Projected Path: 2015: AA/AAA/MLB, 2016: MLB
