    Singleton first came to the attention of scouts and college recruiters in the summer of 2007, when he was 15 and with a wood bat, he blasted a 400-foot home run out of Inland Empire's ballpark. His frame and natural hitting ability have impressed scouts, though his results have lagged behind. At 6-foot-3 and 200 pounds, Singleton has an impressive build, and his large, strong hands indicate natural power potential. He has a sweet, fluid swing, and his bat speed produces an audible "whoosh" as he swings at a pitch. He has struggled to connect with quality pitching at showcase events, and an early-season slump this spring drove down his stock. His backswing can get wrapped and unnecessarily long, leading to problems making solid contact. As the season has progressed, though, Singleton has warmed up. He impressed a group of 30 scouts in an Easter tournament game by ripping several base hits. He has excellent defensive skills, and should be an above-average defender at first base. Singleton is just 17, so a club that thinks it can draw out his terrific natural hitting ability can be patient in developing him. He could also shoot up draft boards in three years if he opts for Long Beach State instead of pro ball.
