Edgar Quero

Quero likely would have made his big-league debut late last season had a mid-August back injury not cost him most of the final month-plus. He made a mechanical adjustment early in the season and slashed .333/.410/.527 with nine home runs, a 15.7 percent strikeout rate and a 9.6 percent walk rate in his final 56 games split between Double-A and Triple-A. That would be a major development for any prospect, but particularly for a 21-year-old switch-hitting catcher in the upper levels of the minors. He's the same age as the college catchers from last year's draft class, yet he'll likely be the Opening Day starter behind the dish, as he'll be eligible to net the White Sox a Prospect Promotion Incentive pick and he doesn't have anything left to prove at Triple-A. Quero's top competition for playing time, Korey Lee, has been worth negative fWAR in all three MLB seasons, but Kyle Teel, who was acquired this offseason from Boston in the Garrett Crochet deal, could join the big-league mix in the first half.
