CHICAGO (AP) – Greg Oden put together a highlight package for NBA scouts and helped No. 1 Ohio State move to the finals of the Big Ten tournament and a step closer to a top seed in the NCAA tournament.

Oden had 17 points, a tournament-record 19 rebounds and four blocks Saturday and the Buckeyes (29-3) pulled away late from scrappy Purdue for a 63-52 victory.

Carl Landry scored 24 points for the Boilermakers, who managed just four baskets in the final 10 minutes _ three by Landry _ cooling off at the wrong time against the talented Buckeyes.

With Oden on the bench after getting his third foul midway through the second half, the Buckeyes got a driving layup from Jamar Butler after a Boilermakers’ turnover and then a 3-pointer from Ron Lewis to take a 50-45 lead with 7:40 to go.

Oden returned and swatted away two shots to add to Purdue’s struggle to score, and when Lewis made two free throws it was 53-45 with 5:29 to go.

Landry broke a nearly five-minute Purdue scoring drought with a jumper, but after another Boilermakers turnover, Mike Conley Jr. swished a 3-pointer from the corner and the Buckeyes were up nine.

Moments later, Oden went crashing through the lane high over Landry and David Teague to slam in a missed shot, giving the Buckeyes an 11-point lead and all but punctuating the victory _ Ohio State’s 16th straight.

The Buckeyes will meet the winner of the other semifinal between Illinois and No. 3 Wisconsin for the tournament title Sunday at the United Center.

Purdue (21-11), losing for the third time this season to the Buckeyes, will have to wait until Sunday’s selection announcement to see if they will make the NCAA tournament.

Oden, who hasn’t decided if he’s going to go pro or return to Columbus for a second season, was 8-for-13 from the field and nine of his rebounds were on the offensive end.

Oden’s 19 rebounds broke the previous single-game tournament record of 18 set by Iowa’s Reggie Evans, who hit that mark twice, in 2001 and 2002.

Ohio State finished with a 49-33 rebounding edge, 21-9 on the offensive end. Lewis added 13 points, Conley Jr. had 11 and Ivan Harris 10 for the Buckeyes.

Purdue, which shot 46 percent in the first half, managed only 28 percent in the final 20 minutes (8-for-29). Teague added 12 points but just six after he hit a pair of 3-pointers in the first three minutes of the game.

Oden had 10 points on 5-for-6 shooting in the first half, displaying an assortment of moves he can take to the next level when he decides to go _ a spin in the lane away from a defender and a left-handed hook; and later a semi-sky hook from the baseline.

But the Boilermakers, who lost twice to the Buckeyes during the regular season, including a tough 63-56 decision at Columbus last month, played aggressively against Oden. The muscular 6-foot-7 Landry hit a couple of jumpers from outside away from Oden’s long reach, and Keaton Grant drove the middle for a floater that went in the basket as Purdue forged a five-point lead late in the half.

But Conley’s driving basket and Lewis’ three-point play helped the Buckeyes recover for a 29-28 halftime lead, despite shooting just 34 percent. Ohio State had a 25-15 advantage rebounding, including 14-3 on the offensive glass in the opening half.
