Polanco was optioned to Triple-A Rochester.
Polanco had an impressive spring as he hit .286 (8-for-28) with a home run. Polanco hit .289/.346/.393 at Double-A Chattanooga last year, but had just a .661 OPS at Triple-A. He was just 21 last season, so he could improve rapidly in his second stint at Triple-A. It's possible he could be a starter in the infield in the majors this summer if injuries strike.
