BOULDER, Colo. -- Spencer Dinwiddie scored 10 of his 17 points in the second half, helping Colorado rally from 14 points down to beat previously undefeated Harvard 70-62 on Sunday.

Josh Scott and Askia Booker each had 12 points and Xavier Johnson added 11, including two key 3-pointers in the second half for Colorado (6-1), which has won six straight since a season opening loss to Baylor.

The Buffaloes ran off 14 straight points over a five-minute stretch, going in front 60-52 with 3:27 remaining, their first lead since the game's opening moments.

Johnson punctuated the run with consecutive 3-pointers and Dinwiddie kept it going with a 3-pointer and a tough running jumper from the baseline.

Kyle Casey had 13 points for Harvard (4-1) which lost for the first time this season. Siyani Chambers added 12 points and Steve Moundou-Missi had 11 for the Crimson.

Casey's layup opening the second half pushed Harvard's advantage to 14 points but Colorado put together a 9-0 run, pulling to 44-39 on Booker's driving layup with 15:46 remaining.

Casey's jumper with 8:41 left to play put Harvard up 52-46 before Colorado suddenly caught fire again.

That's when Colorado went on its 14-0 run.

Laurent Rivard's 3-pointer with 29 seconds remaining pulled the Crimson to within 66-62 but that proved to be Harvard's final bucket as the Buffaloes hit four free throws in the game's final seconds.

Jumpers by Wesley Saunders and Moundou-Missi on successive possessions helped Harvard stretch its lead to 42-30 at halftime.

Harvard put the pressure on Colorado from the outset, bolting to a 16-4 lead during which the Crimson drained four 3-pointers, including a pair by Chambers.

The Buffaloes managed to cut it to 29-25 on a driving layup by Booker before Harvard pulled away again on the strength of 3-pointers from Brandyn Curry and Rivard.
