Mike Yancey and Donald Williams are the lesser known players on the Mission Viejo boys' basketball team, but on Friday they played starring roles.
Yancey hit seven three-pointers and Williams made the final four points in overtime as the Diablos upset fourth-seeded La Crescenta Crescenta Valley, 77-74, in a Division II-AA second-round game at Mission Viejo High.
Mission Viejo (16-10) will meet Woodbridge in the quarterfinals Friday.
Williams, who scored a season-high 18 points, including 12 in the second half, put Mission Viejo ahead for good when he took a pass from Austin Moherman and made a layup with 34 seconds left in overtime.
Williams, a 6-foot-6 junior center, then gave the Diablos a cushion when he made two free throws with 14 seconds left.
Four three-point attempts by the Falcons bounced away.
The Diablos nearly cost themselves by missing their first eight free throws in the fourth quarter. Five of the misses came on the front end of one and ones and another on a lane violation.
Mission Viejo led by as many as 20 in the third quarter, but the Falcons crept back and took a 65-62 lead on a three-pointer by Jake Willis with 2:15 left in regulation.
Yancey made consecutive three-pointers to put Mission Viejo back up by three with 1:31 left. Crescenta Valley took a one-point lead on a put-back by Blake Jacobsen with nine seconds left.
Tyler Kalklosch was then fouled and broke the free throw drought, but missed his second attempt and the game went to overtime.
Yancey, a reserve, scored a season-high 27 points and Moherman had 15. Brock Jacobsen scored 26 and Blake Jacobsen 18 for Crescenta Valley.
