Blair Frederick was the tough-luck loser in Brother Martin’s Catholic League opener last week, allowing three unearned runs and three hits against Rummel.

The LSU signee made sure that didn’t happen again.

Frederick dominated John Curtis, striking out a career-high 13 batters and allowing just two hits in a 3-1 victory Tuesday night at Kirsch-Rooney Staduim.

It was the first District 9-5A loss for Curtis. The Patriots (14-5, 3-1), playing in the Catholic League this season for the first time, defeated Jesuit, Holy Cross and Rummel last week.

“My breaking ball was sharp tonight, and I was throwing it for strikes,” Frederick said. “We knew they were hot, hitting the ball well and beating some good teams. We wanted to bring it to a halt.”

Frederick and the Crusaders (13-2, 2-1) did just that.

The left-hander struck out six straight batters in the fourth and fifth innings. His 13 strikeouts surpassed his previous high of 12 this season against St. Paul’s.

Frederick (4-1) has 50 strikeouts in 30 innings, including the nine he had in last week’s loss to Rummel.

“I just stayed within myself,” he said. “Last game we did a good job but made a few mistakes at the wrong time. But it’s a team game. I knew I had to come back here and do what I do and we’d be fine.”

After a third-inning walk, he didn’t allow another base runner until he walked Jay Curtis in the seventh.

The only hits Frederick allowed were a double by Sean Bretz to start the second inning and an RBI single by Jordin Laruzza in the seventh.

“He had a great night and kept us really off balance early,” Patriots coach Jeff Curtis said. “The balls that we hit found gloves, and that’s going to happen in baseball. Tip your hat to them for playing outstanding defense all game.”

The game ended with Brother Martin turning a double play.

The Crusaders scored in the first inning when Mason Bonnafons walked and stole second. Bonnafons scored on a Curtis throwing error.

They added another run in the fourth. Michael Kirsch led the inning off with a single and later scored on Alex Guidry’s sacrifice fly to right. They tacked on another run in the inning on a double steal when pinch runner Andre Roevens just beat a throw to the plate.

That was plenty for Frederick.

“Blair was very good tonight,” Brother Martin coach Mark Wisniewski said. “One of the things we talked about was dominating both sides of the plate and getting strike one, and he did just that.”

Joel Bergeron had two of Brother Martin’s four hits.

Sophomore Ian Landreneau got the start for the Patriots and lasted 3.2 innings before being replaced by freshman Dax Ford. Ford finished with six strikeouts.

Curtis plays St. Augustine on Friday at Wesley Barrow, while Brother Martin plays at Shaw.

“With (Curtis) on top of the league, it was real important for us,” Wisniewski said.
