Wilken (face) is starting at third base and batting second for the ACL Brewers on Saturday, Javik Blake of Milwaukee's affiliate site reports.
It marks the first time Wilken has taken to the field since April 12, when he suffered multiple face fractures after being hit by a pitch with Double-A Biloxi. Wilken is one of the Brewers' top prospects and his return to action is a good sign for the 21-year-old.
