Skip Henderson scored a Marshall and Southern Conference tournament-record 55 points as the top-seeded Thundering Herd used their fast break in the second half to run away from The Citadel, 121-78, in a first-round game yesterday in Asheville, N.C.

Henderson, who hit 20 of 31 shots and nine of 14 three-pointers, moved within 18 points of breaking the Southern Conference all-time scoring mark of 2,538 held by Furman's Frank Selvy. Henderson, a 6-foot-2 senior guard, broke the Marshall scoring mark of 50, previously set in 1978 by Bunny Gibson. And, finally, he bested the the tournament single-game scoring mark of George Washington's Jon Feldman, 45 points against William & Mary in the 1961 final.

Henderson's previous career high was 46 points against the University of Charleston on Jan. 6, 1986.

The lead changed hands 13 times in the opening half and Marshall (24-6) could manage no more than a seven-point lead at halftime despite Henderson's 20 points.

But the second half was a different story as the Thundering Herd got their transition game going. Rodney Holden scored seven points and Henderson five in a 17-4 run to start the half to give the Thundering Herd a 70-50 lead with 13:48 left.

"That's our type of game -- the fast break," said Henderson. "I was kind of shooting off balance in the first half, but in the second half I got my legs under me.

"I got in the groove . . . ," he said. "They were getting the ball to me for the open shots on the break."

The margin increased to 81-52 about three minutes later after Henderson capped an 11-0 run with a three-point play and a fast break layup.

Henderson left the contest with about four minutes left and 47 points, but returned with 1:19 left after an injury to Andre Cunningham. Henderson, 12 of 16 shooting in the second half, then proceeded to hit two free throws, and two three-point jumpers -- one at the buzzer -- to break the scoring mark.

Wyoming 56, Boise St. 50: Eric Leckner made four free throws in the final 25 seconds as the No. 17 Cowboys recovered from a season-worst 17-point first half and closed its regular season with a win in Laramie, Wyo.

Leckner, who made 14 of his 15 second-half free throws, led Wyoming (23-5) with 22 points. Boise State (22-5) was led by Chris Childs with 16.
