In their latest mock draft (no subs. req’d), Baseball America has the Astros taking Stanford RHP Mark Appel first overall and the Yankees taking prep RHP Walker Weickel with their first round pick (#30 overall). Here’s my write-up. They reiterate that the Yankees are interested in various high school arms like RHP Duane Underwood, RHP Zach Eflin, RHP Lucas Sims, RHP J.O. Berrios, RHP Shane Watson, RHP Ty Buttrey, and RHP Lance McCullers (yes, the son of the former Yankee). The Yanks have $1.6M to spend on their top pick and Baseball America notes that may not be enough to sign McCullers, who has one of the best pure arms in the draft.
