It was a Monday night that College Park will never forget. Even 45 minutes were not enough to decide a winner.

In the second half, No. 5-seed Alabama held a 17-point lead over No. 4-seed Maryland women’s basketball. Xfinity Center was stunned.

Desperately searching for life, head coach Brenda Frese called a timeout with 3:58 remaining in the third quarter. Her team discovered the spark she was searching for.

As time continued to tick off the clock, the Terps’ deficit was slowly erased — and chaos ensued.

“I told them, overtime is our time,” Frese said.

It took the Terps two extra periods to secure the win, but they ultimately emerged victorious, 111-108.

Shyanne Sellers started hot, giving the Terps an early boost in what was an overall strong first half. Sarah Te-Biasu was also impressive, notching eight first-half points. Maryland built a 10-point lead in the second quarter. In fact, it looked to be strolling to an easy victory.

But that was far from the case.

Alabama embarked on a rapid 10-0 run, completely erasing Maryland’s advantage in just over a minute of game time. The momentum was entirely in Alabama’s corner.

Sarah Ashlee Barker was the focal point of Alabama’s offense in the first half, draining 17 points in the opening 20 minutes. She finished with a staggering 45 points, fourth-most in any NCAA Tournament game.

Maryland’s sloppiness and Alabama’s ability to take advantage of mistakes resulted in the Tide taking a two-point lead to the locker room.

Alabama started the second half hot, building a seven-point lead on a 7-0 run. Maryland’s defense was flat-footed, and the Tide made the most of it.

In addition, Maryland’s shots weren’t falling, while Alabama was simultaneously taking advantage from beyond the arc. The Tide’s lead ballooned up to 14, and Maryland found itself in serious danger — Sellers and Smikle were in foul trouble.

Caught in a tough situation, Frese had to burn a third timeout in the third quarter — something she hasn’t done all season.

Alabama’s lead grew to 17, and Sellers committed her fourth foul. Things looked bleak.

“I was trying to be disciplined. I knew my team needed me to stay in the game and honestly, it just comes back to all of them having my back,” Sellers said.

But the Terps showed signs of life nonetheless, going on a small run at the end of the third to cut the deficit to nine. Te-Biasu was instrumental in the effort, knocking down one of her signature clutch 3-pointers.

Maryland needed its run to continue to save its season, all while Sellers was sidelined with foul trouble.

Amari DeBerry saw important minutes in the second half. She began the fourth quarter by recording a huge block on a 3-point attempt, and made a mid-range jumper.

The Terps pushed the pace in the fourth frame, courtesy of a barrage of mid-range shots from Kubek, Smikle and DeBerry. Once the deficit was cut to six, the Tide called a timeout. It was clear now — Maryland had momentum, and was daring to build on it.

Mir McLean was also a huge force off the bench, playing her best game of the season Monday. She got Maryland within a bucket late in the fourth, then Sellers forced a foul and hit two free throws to even the score.

Barker retook the lead with a 3-pointer. But calm as ever, Te-Biasu knocked down a game-tying triple on the other end.

With 12 seconds left and possession, Alabama’s Karly Weathers missed the game-winning shot at the regulation buzzer to send it to overtime.

Both teams went back and forth in overtime, but the Terps were largely in control. The extra period was littered with a few more Te-Biasu 3-pointers, which sent the crowd into a frenzy.

Alabama had the ball down two with 27 seconds to go, and Kaylene Smikle had fouled out for the Terps. But an out-of-bounds play went Maryland’s way with 8.4 seconds remaining.

The ball was inbounded to Saylor Poffenbarger, who had the chance to ice the game after being fouled. She missed her first free throw. Alabama had a chance down three.

On the ensuing possession, Barker put up a 3-pointer at the buzzer, but Poffenbarger was called for a shooting foul.

Barker made all three shots at the charity stripe, and so the game continued into a second overtime period.

The Terps built a five-point lead in the sixth period of play, but the Tide wouldn’t go away.

The two Sarahs — Barker and Te-Biasu — went bucket-for-bucket in the second overtime, and with 28 seconds left, the Terps had a two-point lead with the ball.

Kubek was fouled and split the pair of free throws. Alabama had the ball with a chance down by three. Barker made a pull-up jumper to bring it back down to one.

Sellers was subsequently fouled, and in her final moments at Xfinity Center, she made two free throws.

“I mean, they’re easy money shots. You got to be able to step up and hit them,” Sellers said.

Needing a three, Alabama hoisted up a deep shot. It missed, and the ball ended up out-of-bounds with 1.8 seconds left.

After review, the Tide got the ball, as a Maryland player had touched it last. But the Terps’ stellar defense didn’t even allow a tying shot attempt.

It was simply March mayhem in College Park.

Three things to know

1. “Overtime is our time.” Showing shades of the 2006 National Championship team, Frese used the motto “overtime is our time” Monday. It was a double-overtime, though, Maryland’s first since 2008. It emerged from the rubble with a win.

“This is why you try to earn that right to host and have that energy, because we absolutely needed it with both the double overtimes,” Frese said.

2. 17-point comeback. It seemed like their season was over in the second half, but the Terps embraced the challenges they’ve had all season and found a way to come back.

3. March Kubek. Allie Kubek had the only double-double in the 50-minute game between either team. She was dominant early and often, finishing with 19 points and 12 rebounds. It was yet another huge performance from the graduate student in March Madness.

“I don’t know what it is,” Frese said about Kubek. “I’m here for it. It’s been really special to be able to see, and see it from last year too.”
