The final score of the Brea Olinda-Foothill girls basketball showdown on Saturday night at Foothill High was not indicative of how tight the game truly was.

The second-ranked Ladycats had a nine-point lead with 2 minutes and 20 seconds left in regulation, but Foothill's Christina Marinacci and Blair Shinoda got loose and erased that deficit to force overtime.

The third-ranked Knights were without Marinacci, who fouled out with 39.9 seconds left in regulation, for the extra period and Brea Olinda went on to win, 71-59.

“Anybody that was at the game is going to tell you that it was not a 10-point or 11-point game,” Ladycats coach Jeff Sink said. “If Marinacci doesn't foul out, it's probably one of those games where whoever has the ball last wins. It was a good game. I have the highest respect for the Foothill kids and I have the highest respect for their coaching staff.”

Foothill trailed, 57-48 with 2:20 left after Brea Olinda's Jonae Ervin, who finished with a game-high 28 points, made one of her many acrobatic layups in the game.

Shinoda sank a pair of free throws, then Marinacci knocked down a 3-pointer. Brea Olinda turned the ball over and Marinacci, who had nine of her 22 points in the fourth quarter, drained a jumper to cut it to 57-55 before fouling out.

Ervin missed the front end of a 1-and-1 with 23.5 seconds left.That left the door open for the Knights and Shinoda, who had eight of her 19 points in the fourth quarter, nailed a 12-footer with 4 seconds left to tie it.

Ervin got off a half-court shot that rimmed out at the buzzer and it was off to overtime.

Junior Kelsey Harris, who has been a starter for Brea Olinda since she was a freshman, has struggled with her shot for much of the season, but she made two 3-pointers to start the overtime period.

“It felt good because we needed them,” Harris said. “I was just open so I took them.”

Ervin made 6 of 8 free throws in overtime to help the Ladycats nail down the victory.

“We feel like we're No. 1 in O.C.,” Ervin said. “Foothill is a great team. They worked really hard. They made it a great game. They caused us to make turnovers, but we were able to pick the intensity back up.”
