With only a few short weeks remaining in the regular season, Class 1A girls basketball is the only classification in the state that can boast four unbeaten teams.

That will change this week.

Starting with a big top-10 showdown Friday night, and then followed up with a potential battle of undefeated squads Saturday, business continues to pick up as February draws near. In a crucial High Plains League matchup, No. 3 McClave hosts sixth-ranked Granada on Friday in a rematch of a December tournament contest, and unbeaten and fourth-ranked Fleming hosts 2A’s No. 1 Merino.

Just one day later, Fleming heads to Briggsdale to face off with the No. 2 Falcons in a North Central battle.

McClave (11-0, 1-0) defeated Granada 54-31 back on Dec. 17. The Bobcats (10-1, 1-0) haven’t lost since, and picked up a big 50-41 road victory over now-No. 8 Kit Carson last Friday behind 13 points from Kiana Herrera.

Briggsdale (8-0, 1-0) has posted victories over a pair of top-five programs in 2A this month, including last Friday’s 55-33 victory over Wiggins. The Fleming matchup will likely decide the league champion, but the Falcons also a non-league tilt with top-ranked Flatirons Academy looming Feb. 4.

In 2A, Merino became the last team to drop from the undefeated ranks after falling 59-57 to 1A Stratton on Thursday night. Akron, Wiggins and No. 6 Limon also dropped games in the past week.

In 3A, Colorado Springs Christian and Peyton remained perfect, with the No. 2 Panthers handing Fountain Valley its first loss of the season.

Here is a brief look back at the previous week for Class 3A, 2A and 1A:

Class 3A

Peyton continued its run Thursday night, rolling past the Danes 71-49 in Black Forrest League play. AJ Mannering scored 27 points and Abbie Nickell added 23 for Peyton (13-0, 1-0), which has only six regular-season games remaining.

Colorado Springs Christian (13-0, 9-0 in Tri-Peaks) picked up two more victories, and topped the century mark for the second this season with a 110-point showing Tuesday night. Elsewhere in the league, Vanguard held off a tough challenge from Manitou Springs and has big games looming with St. Mary’s, Fountain Valley and CSCS.

Centauri moved back up to No. 3 in the CHSAANow.com Coaches Poll after upending 4A No. 8 Pagosa Springs 51-37 last Saturday. Amaya Garcia had 17 points for the Falcons (11-2, 4-0 in Intermountain) and Kailyn Polzin had 12 points and 13 rebounds. Abbey Smith followed that up with 22 points in a 75-35 victory over Montezuma-Cortez on Tuesday.

Yuma moved up to No. 7 after defeating previous 2A No. 2 Akron 49-41 last Friday. Caddis Robinson’s 14 points paced Yuma (7-2, 3-0 in Lower Platte), which has matchups with 2A No. 4 Wray on Friday and No. 6 Limon on Tuesday.

While Salida has endured a rough stretch, dropping four of five, the play of freshman Braden Johnson has stood out. In a 67-11 victory over Atlas Preparatory School last Friday, Johnson went off with a monster triple-double of 44 points, 15 steals and 10 rebounds.

Class 2A

With a rash of upsets in 2A the last week, the rankings will likely shuffle a bit headed into next week. Simla’s 51-48 triumph over Limon was among the biggest, as the Cubs (5-6) used a big third-quarter run to pull away. Simla’s six losses have come to upper-echelon teams from 3A, 2A and 1A – on Jan. 13, the Cubs nearly rallied to upend No. 2 Burlington before falling 63-58.

Heritage Christian scored its second big upset of the season, knocking off Wiggins 31-30 last Saturday. The Eagles (8-3) also handed No. 9 Hoehne its only loss of the season in December.

Wiggins (8-5, 1-1 in Lower Platte) will look to bounce back when it resumes league play Friday, hosting No. 8 Sedgwick County.

No. 4 Wray is coming off a 63-37 victory over Haxtun, with Sydnee Cheek and Larissa Salmans combining for 23 points. The Eagles (7-4, 1-2 in Lower Platte) visit Yuma on Friday.

Class 1A

Stratton had perhaps the biggest upset of the week, edging Merino 59-57. The Eagles (5-5) host No. 8 Kit Carson on Friday before finally opening Union Pacific League play Tuesday at Deer Trail.

Kit Carson (7-3, 1-1 in High Plains) dropped its first league game, with Granada posting the 50-41 victory. Another High Plains squad, Cheraw, moved into the top 10 at No. 9 after running its winning streak to seven games. The Wolverines (9-1, 1-0) have been paced by Crislyn Miel’s 11.7 points a game and Abby Provost’s 9.1 points and nine rebounds.

Jenna Krise’s 26 points and 11 rebounds sparked Briggsdale against Wiggins. Krise is averaging 25.6 points on the season.
