The Big 4 recorded a pair of wire-to-wire road wins on Saturday.
The Canisius men held off a late charge by Manhattan to earn a 67-64 win over the Jaspers in Draddy Gym in Riverdale.
St. Bonaventure led from the opening tip and went on to earn a 61-53 win at Richmond.
It was the fourth straight win for the Golden Griffins, who led by 18, 42-24, at halftime. Manhattan went on a 14-3 run to pull within four, 51-47, with about 10 minutes left.
The Jaspers cut the margin to one, 65-64, with 1:20 to play on an Antoine Pearson layup, and each team got a defensive stop. After a timeout, Chuck Harris drove the lane and dished the ball to Menghe a'Nyam for an open layup and a three-point lead with 12 seconds remaining.
Two three-point attempts by Manhattan hit the rim and Canisius took the win.
Canisius improved to 10-10 overall and 5-5 in the Metro Atlantic Athletic Conference.
Second-place Manhattan fell to 7-3 in the MAAC, 10-10 overall.
"We had something to prove to show that we can compete with a team like this," coach Tom Parrotta said. "They are really talented and in the place in the league standings they're in for a reason."
Darnell Wilson led the Griffs with 20 points and 11 rebounds while Corey Herring added 13 points and eight rebounds.
Harris finished with 10 points and five rebounds, and Frank Turner collected 11 points and a 10 assists.
In Virginia, the Bonnies were aggressive defensively, holding Richmond to just 28.6 percent shooting in the first half while taking a 30-16 halftime lead.
"We set the tone from the start tonight and really executed, particularly on the defensive end," Bona coach Anthony Solomon said. "Allowing 16 points in the first half and getting a road win in this conference is great for our team. It's progress."
Michael Lee led the Bonnies with 19 points with Paul Williams adding 10 points and 12 rebounds.
Bona (6-14, 3-4 Atlantic 10) has now surpassed last season's win total in the A-10.
The University at Buffalo (9-10, 1-5 Mid-American Conference) looks to end a three-game losing streak at Eastern Michigan tonight (7 p.m., Radio 1520 AM). The Bulls are 2-6 on the road this season, but have yet to win a road MAC game (0-3). Eastern Michigan is 5-3 at home this year with a 1-2 home conference record.
