WAXHAW — The Cuthbertson girls basketball team stayed undefeated on the season with a 55-34 win over Marvin Ridge at home Tuesday night. The Cavaliers jumped out to a 35-10 halftime lead and never looked back en route to their third win of the young season.

Cuthbertson got a huge performance from senior Kamaria Sheriff, who missed the Cavaliers season-opening win over Sun Valley last week. Sheriff scored a career-high 26 points on 11-of-15 shooting and also hauled in 10 rebounds to earn her first career double-double.

Outside of Sheriff, Cuthbertson made 11-of-40 field goals (27.5%), including 7-of-26 3-pointers (26.9%). The only other Cavalier in double figures was senior Maddie Dillinger, who totaled 10 points on 4-of-10 shooting while also grabbing six rebounds and dishing four assists.

Marvin Ridge (1-1) was led by sophomore Riley Smith, who scored a team-high 15 points, and sophomore Zahra Douglas added eight points.

Cuthbertson plays Piedmont on Friday and the Mavericks will face Parkwood.

Weddington 55, Sun Valley 28

Weddington kept pace with Cuthbertson in the Southern Carolina Conference standings by picking up a 27-point win over rival Sun Valley. The Warriors (3-0) are looking to win at least nine conference games this season for the third year in a row.

Tuesday’s victory marked the fifth straight for Weddington over the Spartans (0-3), who have gone 5-30 in regular season conference play since the beginning of the 2017-18 season. Sun Valley hasn’t finished above .500 in a season since the star duo of Amanda Cherry and Karli Mason led the Spartans to an 18-8 overall record in 2016-17.

Up next for Weddington is a matchup with Charlotte Catholic on the road Friday. The Warriors haven’t defeated Catholic since a 60-50 win more than three years ago on Dec. 15, 2017. The Warriors lost last season’s three meetings with the Cougars by an average of 17.3 points per game.

Sun Valley will host the Cougars next Tuesday. The Spartans lost last season’s three meetings by an average of 23.3 points per game.

Union Academy 59, Queen’s Grant 20

The Union Academy girls opened the regular season last Friday with a 39-point victory over Queen’s Grant. The Cardinals saw three players score in double-figures — seniors Savanna Brooks and Karynton Clark and sophomore Amanda Langkopp.

Brooks led the way with 21 points for the Cardinals, who are hoping to improve on last season’s 18-9 campaign. Brooks passed former Weddington star Karrah Katzbach in career points (1,331) on Friday, according to unioncountyhoops.com, and has a chance to finish inside the top three in county history if she maintains her averages from her first three seasons with the team.

Only two players in county history — Weddington’s Stephanie Watts (2,566) and Parkwood’s Tiffany Brown (2,161) — have scored 2,000 career points while playing for a Union County school.

The Cardinals return to action Wednesday against Carolina International School, which is currently winless on the season. Union Academy has never lost to CIS in nine all-time meetings with the team.
