Out of the match's last tie, 21-21, Serena was called for a double-contact violation and Read set Gonzalez in the middle for a kill.
The third set was especially nip-and-tuck, neither team leading by greater than four points.
"The biggest conversation we had is we have to start picking each other up. Some people are going to have bad games – what are you going to do," Plano coach Lisa Grandgeorge said. "A lot of girls pulled off the bench did a great job, a couple of them playing positions they hadn't got to play all year."
Read set, and also hit when junior Myia Debolt was subbed in late in the first set. Read also sets an even-keeled tone for a Plano team still sorting things out a week in.
"She is very calm, very down to business, gets to work – she leads well by example," Grandgeorge said. "She looked a little fatigued tonight but still plays flawless. She leads group huddles and does a good job with that. She's really figured out how to be a good leader."
