It is great when rookies come up and exceed expectations as Happ did in 2017, even if it was not in full-time duty. Happ was part of the outfield rotation as well as the second-base situation in Chicago as manager Joe Maddon likes to keep everyone involved. His rookie year saw him slug over .500, something only the likes of Kris Bryant and Billy Williams have done for the northsiders. With the great power came the great problems with contact as he struck out in nearly one-third of his plate appearances. The power comes nearly all from the left side (19 of his 24 homers game off righties), but he hits for a better average when put into the game to face lefties. Many rookies struggle at the big-league level when moved as quickly as Happ has been -- he had fewer than 400 plate appearances above A-ball. This kid is special and has more room for growth.
