Syracuse, N.Y. ? The constants for Syracuse this season had been freshman Carmelo Anthony starring on offense and the zone defense struggling to stop teams inside.

The Orangemen, playing hours after entering the Top 25 for the first time this season, had all five starters in double figures and the 2-3 zone was very effective in a 76-69 victory over No. 11 Missouri on Monday.

“We took a big step with our defense today,” coach Jim Boeheim said of his 25th-ranked Orangemen. “And any time you have balance on offense that’s the key to a good basketball team.”

Hakim Warrick had 20 points for Syracuse, which held the Tigers (10-2) to 38 percent shooting, well off their 48.3 mark entering the game and 12 points below their average for the season. The Tigers also had a season-high 20 turnovers.

“It’s tough to have 20 turnovers against a good team and that’s how our opportunities were squandered,” Missouri coach Quin Snyder said. “They make you take some tough shots but we had some open ones we missed, too.”

Ricky Clemons had 26 points, 10 above his season average, and seven assists for Missouri. Center Arthur Johnson, who was coming in off three straight double-doubles including 30 points and 15 rebounds in the last game against Baylor, finished with 17 points and 11 rebounds. But he was never a factor against Syracuse’s 2-3 zone which had been having trouble stopping players inside.

Johnson was 6-for-14 from the field.

“It was a good zone but we prepared for it,” he said. “Those were shots I usually make.”

No. 24 Oklahoma St. 48, No. 5 Oklahoma 46

Stillwater, Okla. — Victor Williams made a disputed bank shot with 3.6 seconds to play, giving No. 24 Oklahoma State a victory over No. 5 Oklahoma.

Oklahoma coach Kelvin Sampson ran onto the court to protest Williams’ shot, which came just as the 35-second shot clock expired. The officials rejected his claims and then Ebi Ere missed a 3-point try at the buzzer.

Williams finished with 16 for the Cowboys (13-1, 2-0 Big 12 Conference), who won their 11th in a row in Eddie Sutton’s 400th game as their coach. Ivan McFarlin had 11 points and 14 rebounds.

Kevin Bookout had 14 and Quannas White 10 for the Sooners (10-3, 1-1).
