The Brewers promoted Adamczewski from High-A Wisconsin to Double-A Biloxi on Monday.
Adamczewski earned the promotion after producing a ridiculous .331/.464/.572 batting line with nine home runs, 10 stolen bases and a 41:40 BB:K in 50 games at Wisconsin. The 21-year-old has made all of his starts in left field this season, but Adamczewski is also capable of handling second base.
