This gets right to the question. As a bad runner and defender, for him to have major league value it's all a question of bat. (Same kind of story with Vogelbach.) Does he have enough bat to justify the rest of his liabilities? Given your premise of average power and mediocre hitting, he's worthless. I'm not sure we know the answer yet, and am open to giving more time to clarify/confirm the answer. If he's going to have value and sustain a big-league career, he'll need to hit well AND show reasonable HR power. I don't expect that, but I think it remains uncertain. I think the HR power is really at the center here. He's a big enough, strong enough guy that he ought to be able to hit HR's. And if his questionable reputation for being able to hit the ball proved true, decent raw power combined with above-average contact should result in above-average HR output. No, he doesn't have Wow power, and if he's not hitting well what power he has won't hit many HR's. But if he can merge hitting with HR's, he may be productive enough to justify his bad speed/defense, at least in a platoon setting. He looked totally outclassed in his Cub debut, very little solid contact or sign of having any gift for hitting. But, small sample size. His PCL numbers are solid and more encouraging. But they aren't great either, there have been lots of 4A guys, big-league useless, who could do upper-.800's OPS in PCL. His numbers this past summer were too scattered, no reason to trust them. If he spend the summer in Iowa, I'd not be shocked if he produced at a steady .900+ OPS there and builds interest; or if he bounces along nearer the .800 OPS mark and erases what little present interest still remains.
