|Warren feared his baseball career was over when a routine physical during his junior year revealed that he had a congenital heart defect. But he was cleared to return to the diamond after surgery and re-established himself as a quality prospect for the 2008 draft. Extremely projectable at 6-foot-3 and 175 pounds, Warren is reminiscent of former Iowa prep standout Ryan Sweeney--and he's more athletic than Sweeney was. Though he still has room to add a lot of strength, the ball jumps off Warren's bat at times. He's an intelligent hitter with a sweet lefthanded swing that catches up to good fastballs. He's an above-average runner and center fielder, and while his arm isn't back to where it was before his heart surgery, it should be average in time. Pro clubs are focusing on Warren as an outfielder, but he could contribute as a two-way player if he attends Oregon State.
