The victory, before an announced turnout of 1,072, kept the Lobos (8-3-2, 4-0-1) in first place in Conference USA competition.
Michael Lisch recorded a conference-best sixth shutout of the season versus the Owls (6-3-2, 1-3-1). Lisch has conceded just one goal in his last four matches in nearly 400 minutes of action.
The match was scoreless through one half, even though the Lobos had a 9-3 shot advantage and 6-0 corner kicks edge.
About 10 minutes into the second half, Wehan broke through, following up a hard James Rogers shot deflected by FAU goalkeeper Theo Jamilloux.
McGovern scored in the 75th minute on a lofted feed from Mathew Gibbons.
“I think what happened today is we wore them down,” UNM head coach Jeremy Fishbein said.
“We had a lot of the ball, and they had to chase. There were more opportunities that opened up, but we had good ones in the first half, too. There’s not an excuse for (not scoring in the first half). We’ve got to take our chances early and force teams to come out and play against us.”
For the second time since the 2007 season, the Lobos have four wins in their first five conference matches. UNM went 10-0 in the Mountain Pacific Sports Federation during the 2011 season.
As a league first-timer, UNM is facing several teams for the first time. Fishbein’s crew is unbeaten in first-ever matchups in 2013, with wins over Charlotte, Villanova and FAU.
New Mexico still has three more first-time opponents left on its schedule.
