GALLIANO –- Fourth-seeded South Lafourche wore down No. 29 Beau Chene during Tuesday's Class 4A first-round baseball playoff game at Eddie Blanchard Field.

Then with two outs in the fifth inning, the Tarpons exploded for six runs en route to a 10-0 mercy-rule victory.

South Lafourche will host No. 13 Riverdale in a best-of-three series in the regional round starting Friday night.

“We practiced all week being aggressive,” Tarpons coach Andrew Ravaglia said. “The little things in the game we had to control them. We controlled the bases. We made plays when we needed to. It all came together.”

“It came down to us making mistakes,” Gators coach Dwayne Thibodeaux said. “We knew if we couldn’t play mistake free baseball against these guys, they were going to capitalize on it. We had a few base running miscues and defensive miscues. They took advantage of them.”

Tarpon pitcher Blake Ougel earned the complete-game win with six strikeouts and four hits. Gator pitcher Beau Louviere took the loss allowing two hits, three walks and three runs in two innings.

Great South Lafourche (24-6 overall) defense snuffed the Gators only two chances to score. Beau Chene (13-19) had runners on the corners with one out in the first inning, but Ougel got Cameron Butts to ground into a fielder’s choice at home plate. Then he struck out Brayden Rodriguez to end the inning.

Thomas Lavergne led off the fifth with a double for Beau Chene. But Ougel struck out Andre Fontenot and got Gavin Domengeaux to hit a line drive to Tarpon first baseman Davin Richoux. On the final out, shortstop Jelby Cheramie made a diving stop on a hard ground ball. Lavergne tried to get back to second base, but Cheramie threw to second baseman Jake Blanchard, who tagged out Lavergne.

“Guys just stepped up. It’s a different guy’s turn every game. They never cease to amaze us,” Ravaglia said. “The runner got confused and was off the base a little bit. Even if you don’t have the traditional play, you always got to back pick or a full arm fake. We got it done.”

“That’s been our season. We’ve gotten guys in position to score; we just didn’t get the key hit,” Thibodeaux said. “We made a poor decision on the base path in both of those situations.”

Meanwhile, South Lafourche exploited their scoring opportunities. In the first, Ougel (1-for-3, two RBIs) hit a bloop single to plate Austin Cantrelle and Kasey Guidry. Mark Pitre scored on a balk call in the second, and Cheramie’s single in the third brought home Pitre for a 4-0 lead.

With two outs in the fifth, the Tarpons came alive at the plate. Beau Callais (2-for-3, RBI) bunt single brought home Pitre, Blanchard scored on a wild pitch, and finally Cantrelle (2-for-2, two RBIs) and Richoux (1-for-3, two RBIs) each smacked two-run singles.

“We’re going to wear a guy down, make him throw six, seven, eight-pitch at-bats,” Ravaglia said. “Then when he gets up in his pitch count and loses a little off his pitches, we’re going to hammer him, make him pay.”

“We just couldn’t make a play,” Thibodeaux said. “That’s been our downfall all season. Giving up a big inning through one or two mistakes, and a hole opens up on us. We couldn’t recover from it.”

South Lafourche defeated Riverdale 7-1 back in early March. But beating them in the playoffs is a different challenge that Ravaglia said he believes the Tarpons are ready for.

“Blake got out with 63 pitches, so he could throw Friday. I just don’t know matchup wise what we’re going to do yet,” he said. “We’re rolling right now. We’re playing our best baseball right now. That’s what you want to do.”
