ROCHESTER, Mich. -- Seldom does a player score just one point and grab six rebounds and still be the difference-maker in a game.

But that's what Duquesne's Shawn James did last night.

The number that jumped off the statistic sheet next to James' name was a school-record 12 blocked shots.

With James swatting shots, Kojo Mensah slashing to the basket for 20 points and 13 rebounds and a relentless pressing, trapping defense, Duquesne ran away from Oakland University, 92-77, last night. The Dukes are 4-0 for the first time since 1986-87 under Jim Satalin.

Duquesne held a block party with a school-record 15 that demoralized the Golden Grizzlies (2-2).

"You feel it's disrespectful if they come in there and score on you," said James, a 6-foot-10 junior who transferred to Duquesne last year after leading Division I in blocked shots in 2005-06 at Northeastern. "Blocks energize our team. It builds up our confidence and makes the other team think twice about bringing the ball inside."

The 12 blocks was a personal high for James, who had 11 three times and 10 five times. The previous Duquesne record was seven by Derrick Alston against Saint Joseph's in 1991 and Ricky Tunstall against Massachusetts in 1980.

In addition to blocking shots, the Dukes altered numerous attempts as Oakland made just 32.1 percent form the field.

"We invite them to come inside on us. We dare them," said Mensah, a 6-1 transfer from Siena who averaged 16.6 points as a sophomore in 2005-06. "We knew they were scared. We could hear them saying, 'pull up, kick it out.' We really wear teams down. They've got their hands on their shorts, and we're clapping and saying, let's go. We're hard to prepare for."

Duquesne's two-platoon substitution system certainly took a toll on Oakland and impressed Greg Kampe, who is in his 24th season as head coach.

"That's the best team to play in this building in 10 years except for Michigan State's Final Four team [in 1998]," he said. "They're better than we thought. It was a game of athleticism. Derick Nelson wanted to prove he could take it over James. James probably will send him a thank-you note."

The 6-5 Nelson was 9 of 29 from the field, with a number of his shots never reaching the basket courtesy of James.

The Dukes crashed the boards for a 66-55 advantage against an Oakland team that had outrebounded its first three opponents of an average of 18 per game. Freshman forward Damian Saunders had nine points and 13 rebounds and freshman swingman Bill Clark contributed 16 points and eight rebounds.

Guard Gary Tucker contributed 18 points that included two 3-pointers and Aaron Jackson had 12 points, 4 rebounds and 4 assists.

Duquesne jumped to a 42-18 lead before Oakland went on a 16-3 run to cut its deficit to 45-34. Jason Duty's 3-pointer made it 48-34 at halftime. The Golden Grizzlies got within 50-40 before the Dukes pulled away and were never seriously challenged.

"Kojo picked it up and carried us home," Duquesne coach Ron Everhart said. "And Shawn James can change the game in a lot of ways."
