BOSTON -- Thanks to 35 saves from freshman Matt O'Connor and a strong effort up and down the lineup, No. 9 Boston University posted a 4-2 victory against archrival and top-ranked Boston College on Friday at Agganis Arena.

The Terriers improved to 8-4-0 overall and 6-3-0 in Hockey East play and picked up their first win against a No. 1-ranked squad since a 4-3 triumph against BC at Conte Forum on Jan. 27, 2006.

BU never trailed in the game, as junior Garrett Noonan opened the scoring near the game's midpoint and sophomore Evan Rodrigues doubled the lead with 3:58 left in the second.

The visitors got on the board just 38 seconds after Rodrigues' score on a goal from senior Pat Mullane, but the Terriers reestablished a two-goal cushion when freshman Matt Grzelcyk converted a wraparound in the early stages of the third.

The Eagles pulled goaltender Parker Milner late in the game to create a 6-on-4 advantage following a BU penalty. The Terriers tacked on an shorthanded empty-netter with a goal by senior Wade Megan to make it 4-1.

Another Terrier penalty gave BC a 6-on-3 advantage, which they cashed in on with 24 seconds left to create the 4-2 final.

BU did not convert on either of its two power-play chances but killed off six of the Eagles' seven chances on the man advantage with the lone exception being the 6-on-3.

BC, which held a 37-34 edge in shots, got a 30-save performance from Milner.
