The Harvard senior class that contributed to three straight Ivy League titles did its part last night to put the Crimson within one game of a fourth. Brandyn Curry, Kyle Casey and Laurent Rivard scored a combined 28 points in reduced minutes to pace Harvard to a 72-47 obliteration of Cornell on senior night at Lavietes Pavilion. Harvard improved to 23-5 and 9-1 in the league to equal the second-best record in school history. Harvard’s win combined with second-place Yale’s loss at Princeton gives the Crimson a two-game lead with three games to play. Harvard can clinch a share of the Ivy title with a win over third-place Columbia tonight and avenge its lone conference loss at Yale on March 7. “That gives us a chance to seize it and clinch it here on our home (court) in our last game,” said Curry. “That adds a little bit more to the game, but we are going to play our game and the league is won on Saturday nights.” Harvard opened the second half with the simple task of preserving a 16-point cushion it created before the break. Cornell scored two quick baskets prompting Crimson coach Tommy Amaker to use a timeout. Amaker’s brief discussion produced the desired result. Junior Wesley Saunders made two free throws and a 3-pointer to spawn a surge that put the Crimson up 56-35 with 10:09 to play. Sophomore Siyani Chambers scored 14 points with four 3-pointers and four assists. The Crimson were on auto pilot the rest of the way.
