STERLING — Morton couldn't solve Sterling's sisters.

Bree, Brooklyn and Josi Borum led Sterling past the Potters volleyball team, 25-12, 25-7 in the Class 3A Sterling Supersectional on Friday night.

"Sterling was a very phenomenal team, and the sisters were definitely the standouts for them," Morton coach Kristen Spangler said. "Not only are they a hard hit, but they are able to place the ball, which I think is crucial at this level. And our block was just struggling to get on tonight. They are just a very good team."

The No. 4-ranked Golden Warriors (39-1) move on to the state semifinals at Redbird Arena in Normal, where they will face Joliet Catholic Academy at 4 p.m. next Friday. Morton (31-9) reached the Elite Eight for the first time since 2006.

In the first set, Morton quickly fell behind 7-3, but tallied off four straight points to bring the match to even at 7-7. But Sterling asserted its dominance behind the Borums.

6-foot sophomores Bree and Brooklyn recorded three straight kills to extend the first set lead to 11-7. 6-1 senior Josi had a kill to make it 17-10 in the first set.

After the Golden Warriors grabbed a 20-10 first-set advantage, Brooklyn had three kills in the last five points to help her team earn the win.

"It's awesome that I have them (my sisters) by my side, and it's our last year playing together to make state for the first time in history," Josi said. "I don't really think it was anything special, we were just spreading out the offense and playing as a team like we needed to."

In the second set, Sterling took control early and never took their foot off the gas. The Borum sisters each had kills to push the lead to 8-2. Eventually the lead was pushed to 16-4 after an ace from sophomore Alexis Rodriguez.

"I just told the girls in the locker room that there are 170 teams in Class 3A volleyball, and 169 of them have to end their year on a loss," Spangler said. "So, its one of those moments where you think only one gets to end with that Cinderella story. So those moments are never easy and you can't let that one loss gloss over the fact that we are Elite Eight out of 170 teams. That is a huge accomplishment, and I am very very proud of this season."

Sterling junior Grace Gould, Bree and Josi each had one kill to push the Sterling lead to 22-6 in the second set. The hosts closed it out from there.

"Just winning it is pretty cool, and the girls worked hard for it. We are just happy to come out on the right end of it," Sterling coach Dale Dykeman said. "We are pretty excited about it, we are having a lot of fun, and we are going to enjoy it. The Borum sisters have been really good for us because they allow us to have phenomenal speed setting, we have power on the pins and are able to run to the right side a ton."

Morton freshman Katie Krupa had three kills and junior Lindsey Dullard had one ace to lead the team. Junior Amanda Lichtenstein added six assists, while sophomore Emme Patton added six digs for the Potters.

Brooklyn had 13 kills and seven digs to lead Sterling, while Josi added 10 kills, 13 assists and nine digs. Bree had eight kills, 15 assists and five digs.

Senior Jaylynn Razo and Rodriguez each added three aces for the Golden Warriors.
