5/8, 5/12: High School Baseball: Dos Pueblos at San Marcos, Buena at Santa Barbara Heading into the final week of the regular season, the Channel League championship is up for grabs. Dos Pueblos (6-4) could stake a claim if it finishes strong in Friday’s finale of a two-game series against San Marcos. The Chargers are coming off a 7-3 nonleague victory over CIF Division 1 power Alemany. San Marcos, the only team without a shot at the title, looms as a spoiler. Santa Barbara (6-4) is awaiting its final league series against Buena (5-3) beginning at home next Tuesday. Buena plays two against Ventura (4-4) this week. 3:15pm. Fri.: Joe Mueller Field, San Marcos High School, 4750 Hollister Ave.; (805) 967-4581. Tue.: Eddie Mathews Field, S.B. High School, 600 E. Canon Perdido St.; (805) 966-9101. Free.
