Stanley, who showed well at the Kenosha Preseason ID earlier this year, was effective at the plate for Puma Academy on Saturday. The righty sent a two-RBI single to the opposite field to give his team the lead late in the game, where they eventually tied with PTA White. Stands at a long 6-foot-3, 175-pound frame, projecting as an athlete and prospect to monitor on the infield in the future.
Stanley was one of the few freshman in attendance on Saturday and made for a good look in his PBR event debut. Standing at a projectable 6-foot-3, 175-pounds, Stanley took a clean round of BP, utilizing flat swing to drive line-drives back up-the-middle. On the mound he syncs up his long levers well and put together a raw ‘pen to finish off his day.
