ETA to majors
When he’s been healthy since signing, he’s shown ridiculous raw stuff, consistently sitting in the 94-97 range, holding his velocity deep into games, and he commands the pitch well. He compliments his fastball with a sharp curveball that is a swing and miss pitch, and a developing changeup. Cosart’s number 1 issue heading in to this season was his durability.
In many ways, Cosart is the pitching version of Singleton. If you watched the Futures Game earlier this month, you saw that Cosart had the second-best stuff in a prospect-laden game after Tampa Bay's Matt More, yet, like Singleton, the numbers rarely match the scouting reports.
Right-hander Jarred Cosart will pitch with a plus fastball at 93-98 mph with a plus curveball that shows good depth and tight rotation, although the Phillies had him tinker with a spike curveball earlier this year that he couldn't command (because almost no one can command that pitch). His changeup is barely a factor at this point, although that could improve with time and usage.
Cosart has first-class stuff, featuring a 94-96 MPH fastball, sometimes higher, along with a strong curveball and changeup. His biggest problem is erratic command, and his makeup has been doubted at times.
Phillies officials have questioned Cosart's maturity in the past, and his command issues led others to believe he was likely to wind up in the bullpen. However, Cosart had the best pure arm in the system, and Singleton the best pure stroke. Those are strong players to build a trade around, and they instantly jump to the front of a painfully thin Astros farm system.
The words "electric" are not said often in conversations with contacts so I perked up when hearing his stuff described as such. Yes, Cosart has a killer fastball/curveball combination, but injury concerns linger and his mid 90′s heat and hammer curveball aren’t missing the number of bats they realistically should.
