ITHACA, N.Y.--Mike Kozak, Steve Williams and Chris Mills scored consecutive goals in the first period and sophomore goaltender John Fletcher made 33 saves to lead Clarkson to a 4-3 upset victory over Cornell in the opening game of their ECAC playoff series last night.

The Big Red (18-8) took an early 1-0 lead on a power-play goal by freshman Trent Andison at 2:01, his 19th goal of the season.

But the Golden Knights (15-13-3), rebounded with three straight goals. Kozak tied the game when he deflected a rebound past freshman goalie Corrie D'Alessio. Williams gave Clarkson the lead, flipping another rebound past D'Alessio and Mills gave Clarkson a 3-1 lead with only nine seconds left in the first period.

Cornell closed to within a goal midway through the second period, but freshman center Mike Casselman scored what proved to be the game-winner 6:07 later.
