Despite his all-out assault on the Low-A South Atlantic League, the reports coming out on Graham Stoneburner might be even better than the stats. In today’s Minor League Update, Kevin Goldstein mentions that the righty from Clemson has “broken out a much-improved slider this year, along with well-above average command.” Back when I profiled Stoneburner during the offseason, reports indicated that he had an average at best slider and command that came and went, so obviously he’s taken a huge step forward early in his career. Whatever tweaks the Yankees had him make, well bravo.
The 22-year-old Stoneburner has a 2.78 FIP with a 43-9 K/BB ratio and a 2.30 GB/FB ratio in 38 IP (six starts), and he struck out 11 in seven innings of work last night. It’s only a matter of time before he gets the bump up to High-A Tampa. The Yanks signed him for just $675,000 as their 14th round pick last year.
