The No. 9 overall pick in the 2015 Draft, Happ homered left-handed against Alex McRae (Pirates) in the third inning and right-handed off Mason Melotakis (Twins) in the seventh inning, with both blasts easily clearing the Scottsdale Stadium fence in right-center. Happ showed good balance and bat speed from both sides, which combined with his solid speed could make him a 20-20 player.
He's less accomplished defensively, with most scouts grading Happ as a fringy defender at second base and believing he's destined for the outfield. He has the athleticism to be an asset on the corners and displayed it in the fifth inning, making a leaping catch on the warning track in left field to deny Mitch Garver (Twins) extra bases.
