ANAHEIM — Freshman pitcher Mia Valbuena held her composure despite seeing the Marina softball team leave 12 runners on base. It eventually took eight innings, but the Vikings beat Esperanza 6-3 in the opening round of the Michelle Carew Classic on Friday afternoon. Esperanza (14-3) is ranked No. 2 in Orange County this week. “We let Mia be Mia,” Marina co-coach Dan Hay said of the team’s freshman standout, who pitched all eight innings and allowed two earned runs on four hits.
