THIBODAUX — UL-Lafayette gave up four unanswered runs, including a walk-off ninth-inning home run by Nicholls State designated hitter Seth Stevens, in a 5-4 loss Tuesday night at Ray E. Didier Field.

The Colonels (33-16-1) outhit the Ragin’ Cajuns (31-20) 10-6. Nicholls first baseman David Zorn who was 3-for-4 with a pair of doubles and scored a run.

Robbie Petty (4-1) picked up the win for Nicholls, tossing two perfect innings in relief with three strikeouts. Nicholls starter Marc Frazier gave up four runs (three earned) on five hits in five innings.

UL-Lafayette freshman right-hander Dylan Moore suffered his second loss of the season after giving up the game-winning homer in the ninth.

The Cajuns took a 1-0 lead in the top of the first as second baseman Stefan Trosclair scored on a Frazier wild pitch. Trosclair reached on a two-out double to left-center, then moved to third on a Colonels error.

First baseman Greg Davis extended the lead to 2-0 in the top of the second, sending a 2-1 pitch from Frazier over the fence in right for an opposite-field home run to lead off the inning. The homer was the sixth of the season for Davis.

The Colonels cut the lead to 2-1 in the bottom half of the third on an RBI single to left-center by third baseman Kyle Reese.

Nicholls threatened in the bottom of the fourth, putting runners on the second and third with one out, but reliever Chris Charpentier got a lineout to third and a strikeout to end the inning and preserve the lead.

UL-Lafayette tacked on a pair of runs in the top of the fifth to get out to a 4-1 lead. Right fielder Dylan Butler launched a leadoff solo homer to left for the first run of the inning. With two outs, center fielder Kyle Clement drove his eighth homer of the season over the right-field fence to give the Cajuns a three-run lead.

The lead wouldn’t last long, though, as the Colonels scored three runs on two hits and a pair of walks to tie the game at 4 in the bottom of the sixth. With runners on second and third and no outs, shortstop Joey Morales lifted a two-run single into right-center off of reliever Colton Lee to cut the Ragin’ Cajuns edge to one run. Two batters later, Darius Knight brought Morales home on an RBI groundout to first base to even the score.

The Colonels put a runner on third with one out in the bottom of the eighth, but shortstop Blake Trahan cut down Zorn at the plate on a ball hit to him by Justin Holt. After Nicholls moved another runner to third in the inning, Moore would come on in relief and get a big strikeout to keep the game tied at 4.

In the bottom of the ninth, Stevens drove the first pitch he saw from Moore over the fence in right for the game-winner. The homer was just the second of the season for Stevens.

UL-Lafayette returns to action this weekend as the Cajuns close out the regular season with a three-game series at ULM starting at 6 p.m. Thursday. The second game is at 6 p.m. Friday, and the two teams close out the series at 1 p.m. Saturday.
