James led all scorers with 20 points in Marquette's 81-76 victory at No. 23 Wisconsin Dec. 8. He shot 7-of-15 from the field and also contributed six assists, five rebounds and a pair of steals in 34 minutes of action.
The victory in Madison was the first by the Golden Eagles at Wisconsin since 1997 and snapped UW's 28-game home court winning streak.
The Richmond, Ind., native claimed the accolade for the third time in his career. He garnered the award on two occasions in 2006-07 and was named BIG EAST Rookie of the Week six times in 2005-06. James is the first Golden Eagle to claim the honor this season.
Marquette returns to the court at 1 p.m. on Dec. 15 when the squad opens a five-game homestand against Sacramento State at the Bradley Center.
