Machado played in the MLB Futures Game in Kansas City last month, going 1-for-3 with a double, two RBI and a run scored. He has been on a torrid pace over his last 10 games at Bowie, hitting .444/.512/.889 with three doubles, two triples, three homers and seven RBIs.
Machado has only played two career minor league games at third -- he's played 203 of his 208 games at shortstop -- but the Orioles aren't moving shortstop J.J. Hardy from his current post.
The Orioles have struggled defensively at third, with Wilson Betemit making a team-high 13 errors at third and Mark Reynolds making six errors at the hot corner in 15 games.
The organization is confident Machado can make an easy transition to third base. He's taken balls at third as often as four times a week over the past several weeks at Bowie.
The Orioles would have to make corresponding 25-man and 40-man roster moves. They will likely option right-handed starter Steve Johnson or right-handed reliever Miguel Socolovich to Triple-A Norfolk and transfer second baseman Brian Roberts to the 60-day disabled list.
Shortly before the Orioles announced Machado was coming to Baltimore, top pitching prospect Dylan Bundy was promoted to Double-A Bowie, furthering the Orioles' 2011 first-round pick's fast track to Camden Yards as a possible September call-up.
