BOONE, N.C. — The Louisiana-Lafayette baseball team couldn’t overcome a six-run deficit Sunday as the Ragin’ Cajuns fell 7-4 to Appalachian State in the series rubber match.

The Cajuns fell to 30-17 overall and 14-9 in Sun Belt play. The Mountaineers improved to 15-34 and 7-19.

“We told them after the big day offensively (Saturday, a 20-6 win) that runs were going to be at premium and that we had to go out and match them, and we didn’t do that today,” Cajuns coach Tony Robichaux said. “We got behind in too many counts and got too much of the plate when we had to make pitches.”

Cajuns starter Wyatt Marks (5-1) took his first loss after giving up three runs and seven hits in 3.2 innings. ASU starter Jeffrey Springs boosted his record to 4-1 by limiting the Cajuns to four runs and five hits in 8.1 innings with five walks and five strikeouts.

Appalachian State outhit the Cajuns 12-5. Mountaineers first baseman Conner Leonard had a home run and three RBIs.

The Mountaineers got on the board first in the second inning. They got back-to-back hits to lead off the inning, a single by Noah Holmes and a double by Matt Brill. Holmes scored on a grounder to first by Brian Bauk to make it 1-0.

Appalachian State added two more runs in the third on an RBI double by Michael Pierson and an RBI single by Leonard.

In the fifth, Dillon Dobson sent his 11th homer of the season over the fence in right off reliever Chris Charpentier to extend ASU’s advantage to 4-0. After a Pierson single to right, Leonard hit a two-run homer to give App State a six-run edge.

The Cajuns answered in the sixth when Greg Davis delivered a two-out, three-run homer over the left-field fence to pull the Cajuns within 6-3. It was Davis’ fifth homer of the season.

Appalachian State got a run back in the bottom of the inning when fielder Brandon Burris tripled with two outs and scored on a Dylan Moore wild pitch.

The Cajuns rallied in the ninth by putting runners on second and third with nobody out after a walk by Dylan Butler and a single by Evan Powell. Nick Thurman brought home Butler on a sac fly to center to make it 7-4, but Appalachian State reliever Robert Whaley got Brenn Conrad to ground out and Blake Trahan to fly out to end the game.

The Cajuns are back home next weekend, hosting South Alabama for a three-game series that starts at 6 p.m. Friday at Moore Field.
