Our No. 21 prospect, Ben Grable, acquired in the Luis García Jr. trade, has a fastball no big minor league pitcher matched all season
Washington got Grable from the Yankees on August 3 as part of the return for Luis García Jr. He's 24, a former Tommy John patient who broke out this year: 2.45 ERA, 46 strikeouts against 8 walks in 33 innings, all as a reliever. His fastball averages 96 mph, touches 99, and generates 20 to 21 inches of induced vertical break, a number no MLB pitcher matched this season. He made the Futures Game before the trade even happened. He's at Double-A Harrisburg now, but a bullpen arm with this kind of stuff and command doesn't stay in Double-A that long. Full breakdown in this free issue of Double Dip.
