Miguel Sano entered Target Field on Friday wearing a pink shirt, hands stuffed deep into his pants pockets and arms pulled in tightly. Twins officials soon scrambled for a closet.

The kid flew up for TwinsFest from the Dominican Republic without a coat. And they needed a coat big enough for his expanding frame.

Sano, the Twins' top prospect and one of the best in all of baseball, has grown an inch in the past year and will be listed in the 2013 media guide at 6 feet, 4 inches.

Sano, 19, said he weighs between 235 and 240 pounds, similar to what he carried at Class A Beloit last season. He's expected to move on to a higher Class A level, Fort Myers, this season. The Twins spent Friday marveling at his size yet still believing that he will be able to stick at third base.

Sano committed 42 errors last season, posting an .884 fielding percentage. Combine that with his expanding frame, and the Twins would appear to have a future outfielder or first baseman on their hands.
