(Straford) threw it in short to Devon and he just hit a great cross," Cooper said. "I was fortunate enough to be in the right spot at the right time."
It gave the Mountaineers (13-7-2) just their second NCAA Tournament win ever and advanced them to a second-round match versus No. 5 ranked and ninth-seeded Akron. The only other NCAA win was in 1981 over UVA. WVU later lost to host Alabama A&M.
WVU's 13 wins ties it with the 1999 and the 1966 squads for the most wins in one season.
"It was one of our better performances," Seabolt said. "We gave up very few chances."
Credit keeper Nick Noble, who recorded his 12th shutout of the season, a school record. It was West Virginia's fourth win of the season by one goal. Noble had two saves. Felice had eight.
Though West Virginia out-shot RMU 28-4, all the Colonials' shots were on goal. WVU had nine shots on goal. Its 28 total shots are a season-best.
The Mountaineers beat RMU (11-8-1) 3-0 in the regular season. The teams were scoreless at the half in this game, though WVU had a 15-3 edge in shots.
"We said at halftime that the best defense was to go forward and make them defend us," Seabolt told MSN. "Some of the shots in the first half were like two pass-backs so they weren't really shots that threatened our goal."
WVU forward Jarrod Smith had a game-high eight shots, four on goal. It next plays at Akron (17-1-2) on Nov. 22 at 7:30 p.m. at Lee Jackson Field.
West Virginia was one of a record seven Big East schools to qualify for this year's tournament. Connecticut, South Florida, St. John's, Providence, Notre Dame and Seton Hall also made the field. WVU has made NCAA trips in 1966, 1968, 1971, 1972, 1973 and 1992.
