The girls basketball programs at Roosevelt and Durango each extended their winning streaks to 13 games over the past week, tied for the longest in the 5A classification.

The Class 3A No. 3 Roughriders have done it behind a powerful, efficient offense. The Demons, on the back of a defensive unit that has caused fits up and down their schedule.

In this week’s look at the big-school classifications, let’s focus on the teams with the longest winning streaks in the 6A, 5A and 4A classifications.

No. 3 Roosevelt -> 13 straight: The Roughriders (13-1) have dominated teams since their opening-night loss at Cherry Creek, scoring more than 70 in seven games during their win streak.

Sophomore Ryanne Bahnsen-Price leads them at 14 points per game on 57% shooting. Madison Moyers is 34 of 73 from deep.

In an 88-15 win over Niwot Tuesday, Kyla Hollier and Bahnsen-Price each had 16 points as the Roughriders shot 52% as a team.

At 10-0 in the 5A/4A Longs Peak League, Roosevelt is a game up on Riverdale Ridge. It’s on the road at Skyline Thursday.

No. 4 Durango -> 13 straight: The Demons (13-1) have held nine opponents to 30 points or less during their streak.

Senior Mason Rowland leads the team with 16.1 PPG on 48% shooting.

Saturday, she nearly doubled up Grand Junction herself in a 40-12 victory, scoring 21 on 8-of-11 shooting.

On the year, the Demons are holding teams to 28.3 PPG. They’re at No. 11 Montrose Friday.

Class 4A

No. 2 D’Evelyn -> 15 straight: The Jaguars continue to impress, beating each of their last six opponents by at least 40 points.

Peyton Marvel … what else is there to say? The uncommitted junior leads the team in points (18.4), rebounds (12.3), steals (5.1) and shooting percentage (55).

In her first game of the season, she had a triple-double with 12 points, 10 boards and 10 steals in a 50-48 win over Denver East.

Her 77 steals are the second-most in the classification.

Friday, the Jags host Littleton, which has the third-longest winning streak in 5A at 10 games.

No. 1 Holy Family -> 13 straight: Fiona Snashall had a double-double with 11 points and 16 boards in Friday’s 49-42 win over then 5A No. 1 Mead.

Another tough test handled by the Tigers (13-0).

Earlier in the month, Holy Family had little trouble with 5A No. 6 Centaurus, holding the Warriors to 23% shooting in a 54-35 victory.

Then Tuesday, it put up a season high in points, beating Greeley West 84-15. Sawyer Dana scored a career-high 35 points (her previous-best was eight). She shot 13 of 22 to go along with seven rebounds and 14 steals.

Thursday, the Tigers get No. 5 Windsor, a team they were swept by in the two-game season series a year ago.

Class 6A

No. 1 Valor Christian -> 13 straight: The Eagles (14-1) win by an average margin of 24.8 points this winter.

Macey Huard, a Montana commit, is second in the class in scoring, averaging 20.9 per game on 46% shooting. Only Grandview’s Sienna Betts is better at 22 PPG.

But other players have been big for the Eagles’ early dominance, too.

Junior Emma Lytle is third on the team in scoring at 9.3 PPG. Her 58% clip is first. Last season, she averaged just over two points per game.

Valor Christian is home against Ralston Valley Friday. It beat the Mustangs 54-30 last Friday behind 17 points and nine boards from Huard.

No. 2 Monarch -> eight straight: Natalie Guanella deserves to be in the conversation for the classification’s best player.

The point guard does a bit of everything, and does it at a high level.

But it will likely be the supporting cast around her that decides how far the Coyotes can go this winter.

Amelia Rosin (11.7 points per game) and Arezo Safi (9.5 PPG) are shooting 51% from the field and Caroline Walley is averaging a team-best 7.4 rebounds.

The three are also a big reason why the Coyotes are among 6A’s best defensive teams, holding teams to 40 or less eight different times this season.

They host Horizon Friday. The Hawks have the third-longest winning streak in the class at seven games.
