GIRLS’ VOLLEYBALL

Harvard-Westlake 3, Flintridge Sacred Heart Academy 0: The Tologs fell to the archrival Wolverines in straight games for the second time this season in Thursday night’s 25-19, 25-15, 25-19 Mission League road loss.

“I think it was more of the inexperience of playing in a harsh environment and just trying to climb over that ledge right there where you see what’s going on and you understand what’s going on, but then it’s putting all of that into actually playing volleyball,” said first-year Sacred Heart Coach Ernest Banaag, whose team slipped to 10-11 and 4-3 in league. “They’re sort of struggling with the fact that they know what to do, but they just can’t seem to put it all together.”
