Under team control for three more years. No need to extend him at all, I like Thomas, but he is not a franchise cornerstone, at least not yet.
Probably never a cornerstone, but a respectable major leaguer. My hunch: .275, .850 OPS on 20 homers. Good fielder. Good ballplayer, though not an all-star. Eventually replaced by Elijah Green, if Green improves and grows at each level. That will be years away.
