Genesis Parker showed up in Arlington Friday morning as O’Connell’s leading scorer.

By seventh period, the sophomore guard was down in Manassas, enrolled at her zoned public school, Stonewall Jackson. Later that afternoon, Parker had her first practice in a Raiders uniform.

[Stonewall] is a lot closer,” Parker said of her switch. “O’Connell is farther away, and it’s just easier to get to Stonewall.”

Raiders senior Nicole Floyd remembers Parker from open gym workouts they attended a couple of years ago. At the time, the rising freshman had narrowed her high school choices down to the two schools in question.

“We were very involved in her transfer,” Floyd said. “There were certain situations going on at O’Connell that made her want to start over for her final two years of high school basketball.”

Parker said she made up her mind definitively on Jan. 9, following the Knights’ 55-24 loss to Paul VI. She’ll play her first game at her new school Tuesday night when the Raiders (5-5) host Hylton.

Parker expects competition to be at roughly the same level, but will adapt to a pass-first role as the 1-guard.

“I need to learn to give other people looks, to run the floor,” Parker said. “That’s going to be more on me.”

Parker averaged 14.7 points per game for the Knights (4-8), more than twice as much than the next highest scorer.

In Manassas, she won’t have to do as much. Floyd, a Wake Forest recruit, is averaging 21 points per game.

“It will make it a whole lot easier,” said Parker, “and hopefully I’ll make it easier for Nicole too.”

Mixon, Floyd nominated for All-American game

When Forest Park senior Amber Mixon received a text message from teammate Dominique Travers early last week, she scrambled to open a link confirming the good news.

Mixon, who leads the Bruins with 12.9 points per game, was one of two Prince William County players nominated for the McDonald’s All-American Game, an annual high school basketball showcase.

“I was pretty shocked, because it is a pretty big honor,” Mixon said. “But I’m glad to see that somebody recognizes me. Hard work pays off.”

It marks the second straight year a Bruin has been nominated. Current University of Virginia freshman Breyana Mason represented Forest Park last season.

Stonewall Jackson’s Floyd was also nominated.
