That game will be played Saturday at 2 p.m. at Emmaus High School.Northern Lehigh head coach Jess Frew made adjustments to her team's corner plays at halftime and it paid off."We changed some things on our corners," said Frew, who also scored her 100th career coaching victory with the win. "We made some major changes, but I said, 'We have to settle down and we have to have a good insert. We need to trap the ball first. And, we really need to just breathe, relax and make things happen.'"We have had good corners, but they weren't executed properly and so they didn't matter. I said, 'Pick it up. Focus on what you're doing. And, finish.' And, they did."The Bulldogs didn't register a shot on their first five corner attempts.It was with 26:47 left in the game when the Bulldogs broke a 1-1 tie.Kayla Brensinger, who starts each penalty corner with a send in for the Bulldogs, scored off a rebound of a Casey Gavalla shot. Catty goal keeper Janae Matos made the save, but Brensinger finished the play.She listened to Frew, trapped the ball, relaxed for a mere second and then fired across from the front right of the Roughies' cage. Brensinger's goal gave the Bulldogs a quick 2-1 lead 3:13 into the scond half.The Bulldogs made it 3-1 later in teh half as Brensinger was on the other end of the successful penalty corner.The Northern Lehigh senior found sophomore Jess Olewine, who capitalized and finished the day's scoring. Meanwhile, Brensinger was credited with the assist."We knew we were coming in here and we were going to have some good competition," Brensinger said. "We really wanted to win this one so we did what we had to do to get the job done. We just worked as a team to pull this one out because we really wanted it."Our goal is to move as far as we can in districts."Megan Covert gave the Roughies an early 1-0 lead with a goal 12:51 into the game.Shorty afterwards, Gavala scored on her first shot of the game with 12:39 remaining before halftime.
