Arcia profile; top 10 prospects

Before the season, the Minnesota Twins planned to have Oswaldo Arcia spend much of the year at Triple-A Rochester. He was just 21 when the season began and had never played at that level.

Even when the Twins called him up April 15, when Wilkin Ramirez took a day of paternity leave, they sent Arcia back down immediately after he went 1-for-3 against the Angels. But the Twins summoned him again on April 17, when Darin Mastroianni injured his left ankle -- and Arcia may never see another day in the minors. He's hitting .286/.318/.476 with three homers and 13 RBIs through his first 23 games in the majors, getting time in both outfield corners.
