The only regret Bishop McNamara’s Corinne O’Conner might have after hitting her first career home run Monday is that she never got a chance to see it go over the fence.

“I was just running and I heard my teammates cheer really loud and it wasn’t until I got to third that I realized it was over (the fence),” O’Conner said.

The two-run blow proved to be the game winning hit during a 7-5 win over East Suburban Catholic foe Marist. It was a back-and-forth game that saw the lead change hands four times.

The Irish (23-0, 13-0) have yet to be pushed to the brink of defeat like they were against the No. 2 RedHawks (15-8, 7-5). The two teams will meet again Wednesday in Kankakee.

“This was a great test for us,” Bishop McNamara coach Laura Harms said. “We have never had a game like this where we had to come back so late.”

The Irish trailed 5-4 heading into the top of the sixth when they scored three runs. A double by Kyleigh Payne, a sacrifice fly by Megan O’Conner and Corinne O’Conner’s blast accounted for the scoring.

The RedHawks’ Julie Trellicoso (3-for-4, 2 runs) made life difficult for Irish lefty Jaelen Hull (17-0). Trellicoso reached base her first three times up and pulled Marist to within a run when she scored on Brooke Wyderski’s two-run single in the fifth. Haley Richy (2-for-3) followed with a two-run homer to give the RedHawks a 5-4 lead.

That erased a four-run third by the Irish.

“We knew coming in they were first in conference and we had something to prove in our heads and we came out strong,” Marist coach Denise Brombereck said. “We’re obviously not in the running for first place (in conference) but we have things we are working on for the state playoffs.

“We are getting better little by little, and hopefully, it will be enough.”
