The main court in the center of UB's Alumni Arena is the home court for both the UB men's and women's basketball teams as well as the volleyball and wrestling teams. Capacity is 6,783 following renovations during the summer of 2004 that included new chairback seating on both sides of the court, renovated bleacher seats on both ends and a new design and resurfacing of the court itself.
A record crowd of 8,971 was on hand to watch the UB men's basketball team defeat Northern Illinois, 90-73, in a first-round Mid-American Conference Tournament game on March 8, 2004. The UB women's basketball attendance record was set when the Bulls hosted North Carolina on November 17, 2000. A record crowd of 4,017 fans, the largest crowd ever assembled to watch a women's basketball game at any of the Western New York-area Big 4 schools, witnessed the Bulls' 95-89 upset of the 22nd-ranked Tar Heels.
In 2011, the University began to renovate the inner-workings of the arena to enhance the game-day atmosphere, adding state-of-the-art sound and lighting systems as well the installation of a new video and scoring system. The eye-catching centerpiece of the renovation is the new four-sided, center-hung LED display, that provides live video, instant replays, and animations.
The displays measure eight feet high and 14 feet wide and will be accompanied by an LED ring underneath which measures 3 feet high and 52 feet in diameter. Rounding out the scoring system will be new fixed-digit displays in both end-zones and seventy feet of LED scorer’s tables at court level. The video board made its debut on Jan. 7, 2012, when the Bulls beat MAC East rival Kent State 66-65.
The men's basketball team recorded a record crowd since the renovation of the arena on March 13, 2015 as 6,607 people watched the Bulls defeat Bowling Green to capture their second straight MAC East Title and a share of the regular season crown.
