A high-profile signing (the Yankees stole Jackson from the college basketball ranks), Jackson made his debut in Low-A last season with unimpressive results. His return to Charleston was headed down the same path this season until Jackson caught fire in June, and he hasn’t looked back, dominating the Florida State League. Jackson has more power than most on this list, and he’ll take a walk when he needs to. The question will be contact. Jackson deserves some credit for cutting down on his strikeout rate from last year–when he whiffed 152 times in 134 games–but I’m not sure I buy it completely. Jackson has just 27 strikeouts in 168 at-bats in Tampa, but can we count on such a torrid streak continuing? Jackson’s strikeout rates in 2008 will be the best indicator of his future.
The article also mentions Brett Gardner, comparing him to Jason Tyner except with more discipline at the plate. That doesn’t bode so well for Brett. But the outlook for Ajax is a bit more impressive.
