Neither defense faltered in a key Seventh Region soccer matchup Thursday as No. 2 Assumption and No. 15 Christian Academy battled to a 0-0 tie.
The host Rockets (11-2-3, 4-0-1) attacked the net early in the second half, but goalie Corine Warlick, who entered the game after halftime, made several crucial saves for the Centurions (6-4-4, 1-2-2).
CAL sophomore Sydney Mathis preserved the tie with a defensive play in the 50th minute. Sarah Schaefer, swarmed by defenders, took a quick shot to the center of the goal, but Mathis kicked it away.
Two minutes later, Morgan Riggs, the Rockets' scoring leader with 17 goals this season, passed to freshman Christen McAllister, whose attempt was wide right.
The duo teamed up again in the 59th minute on what looked to be the Rockets' best opportunity. Riggs flipped the ball back to McAllister as she charged toward the net, but her kick was just wide left.
In the 62nd minute, CAL's Catherine Collins stormed up the middle of the field and drilled a shot, but goalkeeper Kelsey Kaiser made a falling-down save.
With less than eight minutes left, Assumption senior Camille Ogden's free kick sailed left.
"We played a very disciplined, composed game," Assumption coach Kenyon Meyer said. "I was pleased with the way we played. It happens in soccer sometimes: You create a bunch of opportunities, but you just don't finish. I'd rather that happen now than at tournament play."
Assumption kept starting goalkeeper Molly Andres busy in the first half with five shots on goal in the first 10 minutes.
Andres made a leaping save of Ogden's kick in the 16th minute and followed up by deflecting Riggs' 30-footer. Riggs took aim from the right side and lined a shot that bounced off the top of the goalpost.
The Centurions had two opportunities in the final three minutes of the half, including a blast from junior Kenzie Dannelly just before time expired that was stopped by Kaiser.
"We had a few chances," coach John Zutt said. "It's a game of opportunities. We withstood theirs, and we missed on a couple of chances. It was a quality game."
