LAFAYETTE -- In a fast-paced girls basketball game Saturday between Miramonte and Archbishop Mitty-San Jose, it was two freshmen who keyed the Matadors to a 69-55 victory.

Miramonte's Sabrina Ionescu had a game-high 24 points, and Keana Delos Santos scored 15 of her 17 points in the second half at the Campolindo Shootout at Bentley School.

"They are playing like they are seniors. They are not playing like freshmen," said Miramonte coach Kelly Sopak, who also noted the performance of freshman Uriah Howard (eight points). "In the biggest games, they are stepping up."

Miramonte (19-1) was trailing the Monarchs 26-17 in the second quarter when an inside basket by Howard started a 15-4 run to end the half. The Matadors also scored the first five points of the second half for a 37-30 advantage.

Mitty (15-5), the defending California Interscholastic Federation Division II state champions, took a 41-40 lead later in the quarter on a layup by Jahnay Anderson. She also connected on one of her five 3-pointers with 1 minute, 40 seconds remaining in the third quarter to tie the score at 46. She finished with a team-high 17 points.

But Delos Santos immediately responded with a 3-pointer, starting an 8-2 run, and Miramonte led the rest of the game.

Both teams pushed the ball up the floor and applied defensive pressure throughout.

"I think they did a good job reading our defense," Anderson said.

Emily Dinger and Regina Chi scored 13 and 10 points, respectively, for Mitty.
