DUTCHTOWN — Six Gators collected RBIs as 18th-seeded St. Amant High School posted an 8-4 Class 5A bidistrict playoff win at No. 15 Dutchtown on Tuesday evening.

St. Amant (25-9) put the game away with a three-run seventh while Dutchtown was left to lament outhitting the Gators 11-7 while stranding eight runners.

“Both sides said coming in you’ve got to have pitching, defense and timely hitting,” St. Amant coach Troy Templet said. “We seemed to have that with a little luck also today.”

St. Amant advances to regional round play where it will face the winner of Wednesday’s game between No.2 Destrehan and No.31 Fontainebleau.

For Dutchtown (25-10), the loss was a sour ending for a season that brought a District 5-5A championship, including two wins in three regular-season games against league rival St. Amant.

“(St. Amant) set a good tempo for themselves,” Dutchtown coach Chris Schexnaydre said. “They were able to put pressure on us tonight, which has been one of our strengths. We like to put pressure on guys, and that’s something they did (to us) tonight.”

St. Amant left-hander Austin Tanner lasted only three innings in a 13-5 regular-season loss at Dutchtown. This time, Tanner had all the answers as he limited Dutchtown to one run through five innings.

He tired in the sixth and seventh, but, by that time, had enough run support to hold on for the complete-game win.

“It feels great,” Tanner said. “I know they got a hold of me the first time, but I’m glad to get a second opportunity. I’m happy to have my defense playing well behind me.”

St. Amant broke on top with an unearned, first-inning run off of Griffins starter Cole Stapler. Stapler struck out Jacob Morales for what would have been the third out, but Morales reached first when the ball got past Dutchtown catcher Steven Bright.

Morales took third when shortstop Robbie Podorsky mishandled Brennan Grant’s grounder, and scored on Cole Benoit’s single to left.

In the St. Amant third, Matthew Delaune was hit by a pitch with one out and later scored on Grant’s two-out single to right for a 2-0 Gators lead.

St. Amant took advantage of a throwing error and a walk to score two more runs in the fifth. Delaune’s sacrifice fly, and Morales’ infield single knocked in the runs.

Dutchtown had runners at first and second with two outs in the second, but Collin Delaune was caught stealing third. The Griffins had runners at second and third an inning later, but Alex Thibodeaux flied out to end the inning.

Bright hit into a double play in the fourth before Dutchtown finally broke through in the fifth. With Podorsky at second and Adam Boyd at third, Gators shortstop Blaine Schexnaydre couldn’t handle Mason Nickens’ grounder.

Boyd scored on the play, but Podorsky rounded third. Schexnaydre threw home snaring Podorsky in a rundown before he was tagged out.

“We were able to put pressure on them at times, and we had a couple of mistakes on the bases,” Chris Schexnayder said. “I don’t know if we were crossed up with our language or not. Tonight just wasn’t our night.”

Grant McCrory’s two-RBI single got Dutchtown within 5-3 after six innings, but St. Amant came right back. Matthew Delaune reached on a wild pitch after striking out, and a hit batter and a walk loaded the bases.

Boyd walked to force in one run, and Schexnaydre’s single to left plated the final two runs for St. Amant.
