(from Perfect Game USA)Baseball-Reference
One sentence analysis:
The 6'5" lefty only tops out at 85 mph, but with his frame, he has plenty more velocity to gain.
More analysis and notes:
Montgomery throws the standard 4-seam fastball/curve/change-up combination and is working on a cutter.
From USportStar, 4/29/11: Scouting video on Montgomery.
From SportsNetAmerica, 4/29/11: Another scouting video.
From Perfect Game, 8/22/10: "Touched 84 and sat between 82-83, showing a smooth, repeatable delivery, some arm-side run, easy effort, and tight spin on his 2-8, 73-mph curve."
Montgomery has not signed with the Nationals.
