With July coming to an end in just a couple of days, I thought I’d take the opportunity to take a quick look at some of the A’s top-performing prospects over the past month. Lefty Jesus Luzardo has been more than living up to the hype for the RockHounds, while righty Wyatt Marks has been busy putting himself on the map in Beloit. Outfielder Ramon Laureano has been returning to the form that once made him one of the Astros’ top prospects in Nashville, and Eli White, Mitchell Jordan and Sandber Pimentel all merit a mention for their impressive performances as well.
