Over the last two months, the Harvard men's hockey team has lost only once.

To Clarkson.

And now the Golden Knights are the only roadblock the Crimson faces on its way to a second-straight ECAC tournament final appearance.

The two teams square off in the 9 p.m. semifinal game tonight at Boston Garden.

Meet roadblock number one--forward Charlie Meitner.

He's the guy who scored two goals the last time Harvard faced Clarkson.

His first goal knotted the score at 4-4 late in the third period of that game in Potsdam, N.Y., two weeks ago.

His second goal--on a shot that flew past reserve goalie Dickie McEvoy with three minutes gone in overtime--gave the Golden Knights a stunning 5-4 upset of the nationally-ranked Crimson and ended Harvard's seven-game winning streak.

Meitner finished 12th in the ECAC with 13 goals and 19 assists. He recorded 18 goals and 25 assists on the year.

But to Harvard fans, he is best remembered as the guy who delivered the hit that separated Crimson Captain Scott Fusco's shoulder the last time the two clubs met.

"Meitner's their big scorer," Harvard defenseman Jerry Pawloski says. "You really look out for a guy like that. But you can't look out for him all the time. It's the guys you don't look out for that tend to score."

Like roadblock number two--Luciano Borsato.

He scored a power play goal against the Crimson two weeks ago. Not many players have done that this year--Harvard's penalty-killing unit has a 77.4 percent efficiency rate.

Borsato also scored two goals in Clarkson's 6-4 triumph over defending ECAC champion RPI Saturday, to help his team to a first-round playoff sweep of the Engineers.

He has 16 goals and 18 assists on the year.
