This kid is talented, athletic, and real. He's not a bad SS, but will probably be even better at 2B. Gold Glove? Not going to go there. Do you all realize he's still only 25 until July? Seems he's been around forever, but he hasn't.
We could include Kepler when we talk about "thank you" extensions. Unless you haven't paid attentions, this kid is for real. I'm not saying .900 OPS, that's actually crazy. But consistent high .700 and .800-ish? Absolutely!
I stand by my opinion that the Polanco extension was smarter than the Kepler extension (but I wholly support both).
As a shortstop, Polanco is a tweener with the glove. But I think he's going to be a pretty consistent .800-ish OPS guy up the middle as an infielder (give or take 30 points either way based on season). It's better to have that guy at short but also very good to have that guy at second, where his defense isn't as exposed.
It was the best extension the Twins signed this offseason, in my opinion. I expect Polanco to settle in as a .780 guy with a few seasonal spikes through his prime, possibly one or two monster seasons mixed in.
It's a good signing.
