CAMBRIDGE, Mass. -- Siyani Chambers scored 16 points to help Harvard rally past Columbia 56-51 Friday night.

Harvard (18-9, 10-3), which moved into first place in the Ivy League with the win, sits half a game ahead of Princeton, which fell to Yale. The Crimson will secure the conference title outright with a win against Cornell on Saturday and one loss by the Tigers in their final two games.

Harvard trailed 28-22 at halftime but opened the second half on an 8-2 run to tie it 30-30. From there, neither team led by more than three until Grant Mullins hit a 3-pointer to put Columbia (12-15, 4-9) up 49-45 with 6 minutes left.

Both teams went scoreless over the next 4½ minutes but Steve Moundou-Missi sandwiched two free throws and a dunk around a three-point play by Chambers to give Harvard the lead for good, 52-49, with 32 seconds remaining.
