SULPHUR — Teurlings Catholic’s Summer Ellyson was simply dominant in Friday’s Class 4A quarterfinal against Bolton.

The Louisiana-Lafayette signee struck out 17, surrendered only an infield single and pitched a shutout for the Rebels. Ellyson also went 3-for-3 and was a home run short of hitting for the cycle as No. 2 Teurlings Catholic defeated No. 26 Bolton 4-0 in a Fast Pitch 56 state softball tournament game at Frasch Park.

Teurlings will face West Ouachita in the semifinals at 1 p.m. Saturday on Field 16.

“I mean I always want to give my defense a chance to work, but it is a pretty awesome feeling to get 17 Ks in a quarterfinal game,” Ellyson said.

Ellyson set the tone by striking out the first seven hitters she faced. Bolton didn’t get a base runner until the fourth inning, when Lauren Fowler drew a two-out walk. Ellyson responded by striking out Destinee Frazier.

“Summer is leading our team like she should,” Teurlings Catholic coach Lauren Delahoussaye said. “She is a Division I signee, and she is doing what she is supposed to do. And I am proud of her for it.”

While Ellyson was dealing from the mound, Teurlings was having trouble getting runs against Bolton’s Destiny Williams. The Bears junior ace struck out the first two batters she faced and scattered three hits over the first four innings.

“She did a very good job on the mound,” Delahoussaye said. “We had never seen Bolton before and knew nothing of them. That’s always difficult, but we stayed in it. That’s why there are seven innings to the game.”

In the fifth inning, Teurlings broke through as Madison Judice reached base with a single and scored three batters later after Lorin Martin drew a two-out, bases-loaded walk. The Rebels then busted the game open by scoring three more runs in the bottom of the sixth.

“I trust my team completely,” Ellyson said. “I know we were going to come out and start hitting, and I knew we were going to win.”

Ellyson then finished the way she started the game with three straight strikeouts.

Teurlings now turn its attention to advancing to the state title game for the first time since 2013, when the team fell to rival St. Thomas More. That year was also the third straight year that the Rebels played in the Class 4A title game.

“We are pretty confident in our talents,” Ellyson said. “We just need to focus on one pitch at a time. “We just need to worry about that game first and get that win.”
