The Rens jumped out to a 22-10 halftime lead and cruised to a 46-32 win over the WCI Vikings, who are no slouch themselves and considered a certain "top 5" CWOSSA team at this point in the season.
Nyamuoch Teny (10), Tara Deboer (9) and Maya Day (9) paced a very-balanced Grand River attack, while WCI was led by Danielle Sauve who had 11 and Isabella Kellerman (7).
Meanwhile, a couple of other undefeated teams being knocked off on Thursday helped the Rens take sole possession of first place in the WCSSAA junior standings.
Cameron Heights (3-0 entering Thursday) was stunned by WODSS 30-28 after the Crusaders received a strong 18-point outing from Hannah Appleton. Rylee Mitchell-Becker added 5, while Andjela Stankovic (8) and Salome Mekasha (5) led Cameron.
The Bluevale Knights were also on the wrong end of another close WCSSAA junior game.
Despite a 19-point effort from Rachael Hamm, the Knights fell 49-46 in a high-scoring affair to Waterloo SJAM.
Here's a look at the other couple of games on Thursday, keeping in mind that Galt (SSS) and Forest Heights (ECI) received "bye wins":
Huron Heights 28, Preston 27
The Huskies picked up their first win of the season in a tight game against Preston, who fall to 0-4. Kiana Chin (9) and Erica Boer (6) paced the Huskies, while the Panthers received a game-high 12 from Claire Gagne and 4 from Jess Hedges.
Elmira 40, Jacob Hespeler 27
The Lancers moved to 3-1 with a solid home-win against JHSS. Nicole Cressman (17) again led the Lancers, while Sydney Jones added 9. The Hawks received a solid 17-point effort from Jasmine Ramcharan, and 7 from Shianne Riggan.
KCI 39, Glenview Park 12
Alia Hazineh poured in 15 points as the Raiders ran away from Glenview Park. Kristin Hall had 5 for the Panthers.
