One month into the high school baseball season, it's clear which player has made a big jump to emerge as a much-talked about college and professional prospect: center fielder Trayce Thompson of Rancho Santa Margarita. ..... "There's a lot of buzz about him to see a guy that big and strong and how he plays the game real easy," said UCLA Coach John Savage, who signed Thompson in November. Two weeks ago, Thompson hit two home runs when Santa Margarita upset No. 1-ranked Santa Ana Mater Dei, 4-2. Last season, he hit a home run against first-round draft pick Gerrit Cole of Orange Lutheran. "He definitely has all-the-way-to-the-top potential," Santa Margarita Coach Kris Jondle said. "He's a great athlete, loves baseball and is very fluid."
