Asheville (8-6, 3-0 BSC) outscored the Highlanders 12-2 in the final four minutes to remain perfect in Big South Conference play. All of the Bulldogs league wins have come on the road.
Radford lost for the 12th straight time and fell to 3-13 and is 0-4 in league action.
The victory was head coach Eddie Biedenbach's 224th win at UNC Asheville. He moves past Bob Hartman as the school's all-time leader in victories.
In addition, senior guard J.P. Primm dished out three assists to become the school's all-time leader in that category. He now has 521 assists, moving past K.J. Garland (520).
Stephenson was a one-man wrecking crew for Asheville. He also had a double-double with 10 rebounds. The senior forward went 12-of-19 from the field and 8-of-9 from the charity stripe. He was the lone Bulldog in double figures.
"Chris Stephenson was tremendous tonight," stated Biedenbach. "We didn't play well except in spurts but when the game was on the line we got the job done."
With the game tied at 54-54, Asheville ended a four-minute scoreless drought with a lay-up from Jeremy Atkinson to give the Bulldogs the lead for good at 56-54. Stephenson then hit two free throws and scored on a lay-up on Asheville's next two possessions to build the lead to 60-54.
Asheville only allowed one field goal in the final three minutes and went 6-of-8 from the charity stripe to get the win.
The Blue & White won despite its two leading scorers having tough scoring games. Senior guard Matt Dickey was held without a field goal and finished with a season-low six points. Primm went 1-of-7 from the field and contributed six points. He did collect a season-high eight rebounds and picked up four steals, including two in the final three minutes.
Radford hit its first four shots from the field as the Highlanders led 8-0. After a Bulldog timeout, Asheville responded by going on an 18-2 run and built an 18-10 lead. The Bulldogs settled for a 28-24 halftime lead.
"I didn't like the way we started the game as we came out flat and Radford took it to us," commented Biedenbach. "We did a nice job over the next few minutes as we went on an 18-2 run but then we didn't sustain it for as long as we should have."
UNC Asheville returns home to start a two-game homestand as the Bulldogs host VMI Thursday night starting at 7 p.m.
Chris Stephenson has two double-doubles in the last three games as had 16 points and 13 rebounds at Western Carolina last week.

Jeremy Harn blocked a career-best two shots.
Chris Stephenson's 33 points marks the first time a Bulldog player has scored more than 30 points in a game since John Williams had 31 points vs. VMI two years ago.
