After more than two months of basketball, there is another change at the top of the high school boys and girls basketball polls.

Upset wins by the second-ranked teams over last week’s No. 1 teams resulted in the Riverside boys and Scranton Prep girls returning to the No. 1 positions.

Riverside (17-1) defeated Dunmore, 88-71, to reclaim its spot in the boys ranking after three weeks. Scranton Prep (12-5) beat North Pocono, 52-37, and is at No. 1 for the first time since the Week 1 poll.

The teams that lost those matchups didn’t fall far in the polls. Dunmore (16-2), which bounced back with an impressive win over Western Wayne, and North Pocono are ranked at No. 2 this week.

Following Riverside and Dunmore, three Division I teams are ranked and about to embark on a round-robin of games to settle the championship race. Abington Heights (13-5) is ranked at No. 3 and will play at No. 4 Scranton Prep (13-4) on Friday. Before that showdown, however, Scranton Prep plays at No. 5 Valley View (16-2) on Monday. The following week, Abington Heights plays at Valley View.

Holy Cross (10-8), which started as the preseason No. 1 team, endured weeks of adversity with starters CJ Thompson and Adam Badyrka each missing games. The Crusaders had wins over Old Forge and Mid Valley last week and climbed to No. 6.

Old Forge (12-5) is ranked seventh. The Blue Devils have an important week ahead. They play at Western Wayne on Monday and then host No. 1 Riverside on Thursday night.

There are three Division III teams ranked this week.

Elk Lake (17-1), the Division III leader, is at No. 8, Susquehanna (14-3) is at No. 9 and Lackawanna Trail (13-4) is at No. 10.

Lackawanna Trail plays at Susquehanna on Monday and hosts Elk Lake on Thursday.

In the girls poll, Dunmore (15-3), which has 104 straight league wins and leads Division II, is ranked No. 3.

Abington Heights defeated two ranked opponents — Delaware Valley and Scranton — last week to remain at No. 4. The Lady Comets host No. 2 North Pocono on Tuesday in the annual Pink Game and finish the week Friday at home against No. 5 Valley View (14-4).

Last week, Valley View lost to North Pocono and beat Wallenpaupack. The Cougars play at No. 1 Scranton Prep on Tuesday. In the first meeting, Cora Castellani scored 23 points, and Ava Gazoo had 10 in a 45-43 Cougars win.

Honesdale (15-3) and Scranton (7-10) share the No. 6 ranking.

Honesdale defeated Western Wayne and Lakeland last week. The Lady Hornets’ only league loss in Division II came against Dunmore.

Scranton’s losses in Division I came against Scranton Prep, Abington Heights and North Pocono.

Mountain View (13-5) is the Division III leader and is ranked at No. 8. The Lady Eagles face a challenging week. They play at Elk Lake (11-6) on Tuesday and at Montrose (11-7) on Friday.

Delaware Valley (11-7) split its games. The Lady Warriors lost to Abington Heights, but defeated West Scranton and are ranked ninth.

Holy Cross (10-8) earned wins over Old Forge and Mid Valley to remain ranked at No. 10.
