SAN DIEGO — New Mexico came through with clutch hits against BYU, winning 5-4 in 11 innings on Tuesday to open the Mountain West Conference Baseball Tournament.

The Cougars turned six double plays, but a pinch-hit home run in the ninth inning by the Lobos' Jacob Nelson and a game-winning single by Trey Porras with one out in the 11th inning secured New Mexico's victory.

BYU, now 29-26 overall, led twice in the game, taking an early 1-0 lead in the first inning and a 3-1 lead in the sixth.

New Mexico's DJ Peterson doubled in the gap to tie it at 1-1 in the fourth, but the Cougars escaped further damage in the inning when BYU catcher Alex Wolfe held on as he was bowled over at the plate to help Jaycob Brugman turn the first of his two double plays in the game from right field.

Brugman turned his second double play, and his fourth of the year, when he closed the sixth inning on a fly-out to right field and threw to first base to double up Luke Campbell. BYU first baseman Austin Hall was on the tail end of five of those double plays.

Hall also hit a one-out RBI double to score a Ryan Bernal and give BYU a 2-1 lead in the sixth. Hall then scored after stealing third and coming home on a double by Wolfe, giving the Cougars a 3-1 lead.

BYU never led after that, but did get a 4-4 tie in the ninth when Dane Nielsen singled in pinch-hitter Alex Hancock to force extra innings.

BYU starter Matthew Neil was effective through eight innings, walking none.

"We are really disappointed not to come out with a win," said BYU coach Vance Law. "The pitchers from both sides fought well, but we were not able to come up with the big hits with two outs. That's the way baseball is sometimes; the breaks went New Mexico's way.

"We `burned' a couple of our pitchers and have a rough road ahead, but it can be done because we have enough pitching depth. Our defense was great with a couple of heads-up plays. We will bounce back and be ready."

The Cougars play again today at 11 a.m. in the double-elimination tournament.
