LAFAYETTE — Behind Whitney Romero’s no-hitter, St. Thomas More blanked South Terrebonne 9-0 on Monday to open the Class 4A softball playoffs at Lady Cougar Softball Field.

“It’s hard to beat a team when you can’t hit the ball,” STM coach Andria Waguespack said. “(Romero) threw exceptionally well today.”

Waguespack also gave credit to pitching coach Danielle Price.

“We had an outstanding pitching plan and set up our defense exactly where we needed to,” she said. “Can’t ask for better than that. I’ve got one of the best pitching coaches, hands down. It makes us very tough to beat.”

Romero came out firing early, retiring the side in the first on just eight pitches.

With Romero setting the tone in the circle, senior catcher Bailey Hemphill did the same at the plate in the bottom half of the inning sending a 2-0 offering from South Terrebonne’s Mikenzi Authement over the wall in center giving STM (18-9) a 1-0 lead after one.

The home run was Hemphill’s only hit of the game. She walked on 12 straight pitches in her next three at-bats.

“You can’t hide Bailey (Hemphill), everyone knows her now,” Waguespack said.

Julia Laperouse led off the second inning with an infield single, but back-to-back outs put STM’s inning in jeopardy. After Laperouse stole second, STHS (14-12) decided to walk Hemphill, giving STM runners on first and second with two outs.

From there, STM strung together four straight hits as Paityn Desormeaux singled to left, scoring Laperouse. Romero smacked a double, bringing home Hemphill, and Tressie Mouton, who replaced an injured Courtney Bourque, followed with a two-RBI single to give STM a 5-0 lead. Gillian Harvey followed with a single, but Mouton was thrown out at third to end the inning.

The five-run cushion was more than enough for Romero, who fanned 13 while facing just one over the minimum. South Terrebonne’s only runner came following an errant throw on a dropped third strike.

While STM’s biggest offensive outburst came in the second inning, the Lady Cougars were able to constantly add to their lead. STM scored in all but one inning. The Cougars scratched two runs in the third, one in the fifth thanks to Katelyn Norse’s solo homer, and for good measure, a run in the sixth inning.

STM will host No. 9 Belle Chasse on Saturday after Belle Chasse defeated Northwood 2-1 on Monday.
