Ian Hummer scored 21 points and hit the game-winning layup with 3 seconds left to give Princeton a 59-57 win over Rutgers in Piscataway last night.

Douglas Davis added 16 points and Denton Koon 10 for the Tigers (4-5), who let a 17-point lead evaporate in the final seven minutes and had to rally for the win.

Eli Carter had 17 points and sparked a furious comeback for the Scarlet Knights (4-5), who lost their second straight and dropped below .500 for the first time this season. Myles Mack added 11 for Rutgers.

Princeton had its largest lead at 49-32 with 7:58 remaining and led 52-37 when Carter scored seven straight, igniting a 15-0 Rutgers run that tied it with 2:33 left.

After Carter made 1 of 2 foul shots to tie it again at 57, Princeton called timeout with 14 seconds left. Davis then threw a pass to Hummer, who spun into the lane and drove for the layup. Jerome Seagears’ desperation 3-pointer fell short.

Hummer added eight rebounds and five assists, and T.J. Bray had eight rebounds and four assists for the Tigers.

In winning its third straight and beating its long-time in-state rival for the second straight year, Princeton snapped a five-game losing streak at Rutgers.
