New Trier coach Scott Fricke walked out of the locker room and immediately asked us if his hair looked gray. After the Trevians' last two games, he might go bald before the season is finished.

New Trier (4-4, 2-0 CSL South) gave up a nine-point lead in the final 90 seconds of regulation, missing five straight free throws and failing to get stops defensively.

But the Trevians responded in overtime and held on for a 61-58 win, their second straight CSL South victory.

"I'm not concerned with [the missed free throws] and I don't think the rest of the year we'll miss five free throws in a row," Fricke said. "Where I'm really disappointed is our defense let us down at the end of the game."

In stark contrast to the final 20 minutes, New Trier's defense was solid in the first half. They held Glenbrook South to 20 points and were more active in their movement and communication.

Their offense was a different story. New Trier started the game with three consecutive turnovers and struggled against Glenbrook South's defense.

It didn't help that junior center Connor Boehm was hobbled by back spasms; an injury that flared up during his Friday physics class.

"I was spread-eagle on the floor and they had to wheel me down to the nurse's office," Boehm said of his injury earlier on Friday. "I thought going into about 6:00 [p.m.] that I wasn't going to play tonight."

But Boehm gutted it out and ended up leading the Trevians with 25 points. Although Boehm said his back spasms didn't bother him too much during the game, he spent more time on the perimeter rather than battling in the paint.

In between a pair of layups, Boehm knocked down a rare three pointer, giving New Trier a 17-15 lead. They finished off the second quarter with a 10-1 run and went to halftime up, 27-20.

"We weren't going to let Connor Boehm have his high-low seals and we did a nice job taking that away," Glenbrook South coach Scott Nemecek said.

After giving up only 20 points in the first half, the Trevians allowed 17 points in the third quarter alone. The Titans consistently got penetration into the lane and Glenbrook South trailed by four entering the fourth quarter.

The Trevians added to their lead and went up by nine after a layup by Boehm. But they failed to score a point in the remaining 90 seconds.

In the final minute, Boehm, David Bragiel and Matt DiCesare missed the front end of single-bonus free throws while Glenbrook South continued to cut into lead.

After getting fouled by Boehm inside, Glenbrook South's Jack Ryan sank two free throws and tied the game at 54-54 with 3.9 seconds remaining.

But in overtime the Trevians responded. Boehm was fouled with 9.4 seconds to go and hit two free throws to put New Trier up by three. DiCesare blocked a desperation three-point attempt by the Titans and New Trier escaped with a victory on the road.

Boehm led the Trevians with 25 points and Bragiel chipped in with 11 points. Ryan paced Glenbrook South with 16 points.

Glenbrook South plays Palatine High School on Saturday.

"We've done a great job scrapping and being tough, playing good defense for the most part," Boehm said. "We'll get a couple back and I think we'll be a dangerous team."
