|Harrison established himself as one of the top power hitters in Southern California early, homering off future Rockies first-rounder Tyler Matzek with a wood bat as a freshman in scout ball. He easily rates as the region's best high school bat this year. Harrison has a physical 6-foot-2, 215-pound frame and above-average righthanded power potential. Some scouts think he could be an above-average hitter, too, if he does a better job protecting the outer half and adjusting to breaking balls. He can make loud contact, but he centers balls on the barrel inconsistently, and other scouts see him as just an average hitter. It's unclear where he'll play on the diamond. His arm has improved to the point that some scouts now consider it average, but his actions at third base are stiff and his range and footwork are fringy. He'll get a chance to stay at the hot corner, however, before falling back to first. He's a below-average runner with solid instincts on the basepaths. Harrison plays hard and loves to compete, and scouts expect a club to buy him out of his commitment to Southern California.
