The Houston Astros are already surprising many with their better-than-expected play so far this season. But they're still preparing for the future and are the holders of the No. 1 overall pick in the 2012 MLB Draft this summer.

In the latest mock draft over at Baseball America, Jim Callis ties the Astros to a familiar name. As most analysts have predicted, Stanford Cardinal right-handed pitcher Mark Appel is still expected to receive the coveted No. 1 overall selection.

Appel is currently a junior at Stanford and has been turning heads during his time there. Perfect Game lists him as having a fastball that normally clocks between 88-92 mph. He is reported to be a good athlete with a plus slider.
