#5. Mac Williamson – OF, 23 yo, Hi-A: The Giants took Johnathan Mackensey “Mac” Williamson in the third round of last year’s draft out of Wake Forest, where he was a 1st Team All-ACC selection as a redshirt junior in 2012. In his three seasons with the Demon Decons, his right-handed bat hit 36 HR, including 17 his final year. Upon signing with the Giants, the collegiate power hitter was assigned to the Arizona League, where he dialed up the long-ball twice in four games. He was quickly bumped to Salem-Keizer in the NWL, and continued to hammer professional pitching for the rest of the summer. Between the two levels, Mac hit .321 with 9 HR in 33 games, enough for most prospect hounds to take notice. He was assigned to San Jose this season, and has really heated up since the end of May. In 51 games between April and May, he hit 6 HR with 56 K’s. In 42 games since, he’s hit over .300 with 11 HR and 46 K’s. While the strikeouts are still higher than you’d like to see, he’s raised his OBP to .356 and has really flashed his power this summer.
Let’s keep something in mind: The Giants don’t have any elite hitting prospects in their system, but they do have some guys who profile as above average big leaguers. Williamson tops the list, as he’s not only built like a brick (6’5”, 240 lbs), but he offers probably the best power bat in the organization, along with the athleticism to play all three outfield positions. From what I’ve read, he’s got a great arm to boot… BA ranked him the #1 pitching prospect in North Carolina his senior year of high school. At this point, his biggest weakness (and probably the thing that kept him from being a 1st round pick) is his contact rate, which will likely never be amazing. However, if he can continue to get on base and hit for power, he’s got a future in a Major League outfield. He’s starting to show off his tools on a nightly basis, and you can bet the Giants are taking notice.
