It's playoff time, so why not turn loose the best girls' soccer player in California.
Unbeaten Studio City Harvard-Westlake unleashed sophomore Alyssa Thompson on Tuesday in a Southern Section Division 1 quarterfinal against Temecula Valley, and Thompson responded by scoring six goals in a 6-3 victory.
Thompson came in having scored 30 goals on the season. She's one of the quickest players and used that speed to dominate.
"What do you say?" Harvard-Westlake coach Richard Simms said. "She leaves you a little speechless. Some are spectacular runs and some are spectacular shots and some are spectacular composure. She's pretty dynamic."
