NEW YORK (AP) — Wesley Saunders scored 21 points and Harvard rebounded from a loss at Cornell to beat Columbia, 80-70 Saturday night and set up a first-place showdown at home against Yale in the penultimate Ivy League game Friday night. Harvard (20-6, 10-2) owned sole-possession of first place prior to the 57-49 loss and the Crimson wasted little time in making up the lost ground, opening the game on a 17-9 run that ballooned to a 37-24 advantage at halftime.
