Defending Class 5A champ Roosevelt’s 15 straight wins is currently the longest on the state’s girls’ basketball scene. Little surprise there.

Pagosa Springs being tied for 4A’s biggest streak at 12 — that’s a bit more head-turning after the Pirates went just 10-14 a year ago.

In this week’s look-in on girls’ basketball, we go over which teams haven’t lost in ages from the 6A, 5A and 4A classifications. Some are predictable. Some not.

Class 6A

No. 6 Pine Creek; Win Streak: 9: The Eagles (14-3) haven’t lost since Dec. 19, winning nine straight and seven by double digits.

Brooklyn Stewart (20.1 PPG, 11.6 RPG) had at least 20 points in five of her last six games coming into Tuesday’s 51-41 win over Doherty. Coming into the week, the junior was shooting 50% from the field with nine double-doubles.

In a win over Vista Ridge last Wednesday, she had 21 points on 8 of 14 shooting, as well as a season-high 18 rebounds.

Pine Creek will look for its 10th straight win of the season at Fountain-Fort Carson Thursday.

No. 3 Cherry Creek; Win Streak: 8: The Bruins (14-2) lost at Pine Creek Dec. 21 before rattling off eight straight wins, including two against current top-10 6A teams (No. 7 Regis Jesuit and No. 9 Mullen).

A marquee matchup with defending champ Grandview, 6A’s fourth-ranked team, takes place later Wednesday night.

Going into it, Tianna Chambers is averaging 15.3 points, shooting 50% from the field and 41% from 3-point range. She scored 19 against Mullen on Jan. 19, going 5 of 10. She had 15 on 6-of-8 shooting against Eaglecrest Friday.

Class 5A

No. 1 Roosevelt; Win Streak: 15: The Roughriders (15-1) won the 5A title last winter, and they have arguably been even better this season with their entire starting lineup returning.

Their defense has been stellar, allowing 35 points or fewer in 13 of 16 games. The exceptions being their opening-season 45-43 loss to 6A No. 3 Cherry Creek, a 77-64 December win over 5A No. 6 Windsor, the team it beat in last year’s 5A finals, and a 75-45 win over 4A No. 3 Riverdale Ridge on Jan. 20.

Coming into the week, sophomore Kyla Hollier (16.4 PPG, 7.3 RPG) led five Roosevelt players averaging 9.9 points or more. Ahead of Tuesday’s 72-35 win over Thompson Valley, she had at least 12 points and eight boards in three straight games.

They’re home against No. 8 Frederick Wednesday.

No. 4 Northfield; Win Streak: 11: The Nighthawks (15-1) look like they’re going to be a power in Class 5A for a long time.

With their lone loss of the season coming to 4A No. 2 D’Evelyn Dec. 9, they’ve been led in scoring by a pair of freshmen in Madison Bethel (10.6 PPG) and LaPorsha Allen (10.1, 6.8 RPG).

Bethel has averaged 13.7 points over her last three games, going 18 of 23 from the field during it. Allen has five double-doubles this season.

Northfield is home against Regis Groff Wednesday.

Class 4A

No. 6 Pagosa Springs; Win Streak: 12: Junior Elizabeth Currier scored in double figures in six straight games for the Pirates (13-3) before finishing with seven points in a 41-38 win over 3A No. 7 Centauri Saturday.

With her and others having nice seasons, the Pirates are rolling, building off last winter when they finished the regular season with five straight wins before falling to Resurrection Christian 44-41 in the opening round of the playoffs.

Having not lost since early December, the Pirates edged the Falcons for the second time this month on Saturday to take a two-game lead in the 4A/3A Intermountain League. They also beat Centauri 44-39 Jan. 12.

Pagosa Springs is home against Ignacio Friday, then Alamosa Saturday. It beat both teams by double digits earlier this month.

No. 9 Delta; Win Streak: 12: The Panthers (12-4) have already ensured themselves a winning season, the program’s eighth straight dating back to 2015-16.

Senior Kylie Huff had taken all but two of her shots from inside the arc coming into last weekend, scoring a team-best 11.4 PPG on 48% shooting.

Before wins over Summit and Rifle over the last four days, which stats were not immediately available, Huff had scored in double figures in four straight games. Friday, she had 12 points on 5-of-7 shooting in a 68-point win over Basalt.

The Panthers, currently atop the Western Slope League, are at Steamboat Springs Friday. They beat the Sailors by 36 on Jan. 12.
