That gave the Lions (13-6, 2-0 Ivy League) a sweep of their travel partners to open league play. A week earlier Columbia used a 16-4 run in the second half to beat the Big Red (1-15, 0-2) 71-61.
The Big Red went up 51-49 midway through the second half before Columbia ripped off eight-straight points, four by Lo. After a Cornell bucket, the Lions scored nine straight, four by Rosenberg.
Columbia went 10 for 10 from the line in the last 1:12.
