The 11th annual Perfect Game All-American Classic took place Sunday evening at Petco Park, and as usual, it featured a large percentage of the top prep prospects for next year's draft. Here's a rundown of some of the guys who stood out at this outstanding event.

• Shepherd, Texas, right-hander Tyler Kolek, all 6-foot-6, 245 pounds of him, showed big velocity yet again. He worked 93-97 mph, throwing just one off-speed pitch in an 81 mph curveball. Assuming he stays healthy, he'll probably be the first prep pitcher taken next spring because of his sheer size and fastball. However, other guys in the class have better feel or command.
