I can't decide. On the one hand, he's cut his strikeout rate while maintain his walk rate in each of the previous two years. On the other hand, it took him 1000 at bats to get out of high-A ball. On the one hand, he had a great month once he was promoted. On the other hand, he struck out 27 times in 87 plate appearances and had a BABIP of .365. So he was swinging out of his boots and probably a little lucky, which probably won't continue.
I doubt he's ever going to be more than a reserve outfielder with pop, but I guess if we're lucky he could have Marcus Thames' career (surprisingly good some years, pretty bad some other years, never a guy you're building your team around or you're not willing to replace if a better option comes along).
I'm hoping to be pleasantly surprised by how he turns out. He's young and talented enough to have substantial upside if he improves his pitch recognition. He's never going to hit for a high average, but maybe .260/.340/.480 with good defense is possible.
