O'Boyle's 3-point basket at 7:29 in the first half pushed him past the 1,000-point barrier. The Scranton, Pa. native is the 48^th Leopard to reach 1,000 points.

American's Matt Rogers cut the deficit with five points in the final minute, still trailing 33-17 at the end of the first half.

The Eagles opened the second half with a 7-2 stretch, sitting 11 points behind the Leopards at 16:00, 35-24.

A string of four consecutive successful Lafayette 3-point shots gave way to a 49-30 advantage at 11:50. The Maroon and White were shooting 63 percent from three-point land at that point in the game.

American's Elijah Stephens and Geoff Sprouse each sank a 3-pointer to close the gap to eight points, 58-50 at 5:16. Stephens added four more points by 2:25 as a part of a 10-0 run to hone in on the Leopards, who held the slim 58-57 advantage.

The Eagles stole the lead, 59-58, with 0:49 on the clock, but a free throw from Vander Baan earned a tie at 0:22. The Eagles took a timeout with 19 seconds left. American set up a final shot for Rogers, but Vander Baan rejected it and sent the game into overtime. 

Rogers opened the extra minutes with a 3-pointer at 3:07 and a hook shot at 1:26, followed by two free throws by Vander Baan. The Eagles led 66-63 as time was running out, but O'Boyle buried a 3-pointer with four seconds left, 66-66, to end the first overtime period.
