SAN DIEGO, Calif. -- Third-seeded UCLA exploded for four second-half goals en route to a 5-0 victory against Kentucky in the second round of NCAA tournament on Friday. Senior midfielder Chelsea Cline came off the bench to score two of the Bruins' goals after intermission.

Ally Courtnall put UCLA ahead 1-0 with a goal at 38:27. Courtnall received a loose ball in the box and shot to the far right of the net for her fourth goal of the season.

The Bruins took a 1-0 lead into halftime and quickly put some distance between them and the Wildcats. Cline, who came in as a substitute in the first half and started the second half, scored a pair of goals seven minutes apart. Cline's first goal at 51:56 curled to the upper far post from about 20 yards out. Her second goal came when she stole an errant back pass and headed the ball into an open net from 12 yards out at 58:11.

Kylie McCarthy increased UCLA's lead to 4-0 at 72:55 by sliding in a cross from Courtnall from five yards out for her first goal of the season.

Freshman Kodi Lavrusky scored in the 87th minute, recording her second goal of the year with a curling shot from the left side to the upper right corner from 13 yards out.

"I'm really excited for multiple reasons," UCLA head coach B.J. Snow said. "Certainly the win is great; we scored some good goals. I'm proud of the way we played soccer-wise, but more importantly, I'm really proud of the way we competed for 90 minutes. Every single one of them.

"It didn't matter who was in the game; everyone competed as hard as they possibly could. In the NCAA tournament, that's more than half the battle. From that standpoint, I'm really, really happy. We're going to enjoy it for an hour and then we're going to get ready for Sunday."

With the win, the Bruins improve to 17-2-2. Kentucky ends its season at 14-7-1.
