Box Score
ANN ARBOR, Mich. -- JaJuan Johnson scored 22 points, E'Twaun Thomas added 20 points and No. 12 Purdue opened the Big Ten season with an easy 80-57 victory over Michigan on Tuesday.

The Boilermakers (12-1, 1-0 Big Ten) also got 17 points from Ryne Smith and 10 from Terone Johnson.

Michigan (10-3, 0-1) was led by Stu Douglass with 15 points, but no other Wolverine reached double figures. Michigan shot 38 percent, compared to Purdue's 49 percent, and turned the ball over 14 times.

Michigan point guard Darius Morris, the Wolverines' leading scorer, was held out of the starting lineup for what John Beilein called ``disregarding some of our core values.'' Morris eventually played 32 minutes, finishing with nine points on 3-for-14 shooting.

Purdue took advantage of Morris sitting out the first 4:05, by racing out to a 19-3 lead. Douglass, who started in place of Morris and then played beside him in the backcourt, led Michigan's rally with 13 first-half points.

The Wolverines briefly led 26-25, but Purdue scored the final five points of the half to take a 30-26 advantage.

The Boilermakers stretched the advantage to 38-28 early in the second half, and Michigan struggled to put together a sustained run on offense.

Purdue used several fast-break dunks to key a 17-2 run that turned the game into a rout in the final eight minutes.
