GLENPOOL - One and one equals two - except when you are trying to get into the next round of the Oklahoma Class 4A football playoffs.
Grove and Glenpool will be using that math Saturday night when they square off in a second-round clash. Kickoff is set for 7:30 p.m.
The winner moves on to a semifinal date against either Star Spencer (8-3) or Wagoner (10-1) at a site to be determined.
If its Wagoner and the Ridgerunners, it would be a rematch of a Week 9 battle that saw Wagoner claim a 28-21 decision.
This is the second straight year the teams have played in the quarterfinals.
The Ridgerunners claimed a 35-29 victory here last year.
Glenpool took a 22-14 lead with 10:50 remaining on a 12-yard run by Mike Wright and his ensuing conversion run.
But the Ridgerunners scored on three consecutive possessions to reach the semifinals for the first time since 1978.
The 21 points came in the span of 6:11 on a 39-yard run by Colton Gehrke, a 65-yard TD catch by George Maymi and a 3-yard bust by Gehrke.
The Ridgerunners beat Poteau 30-25 tye following week in Tahlequah then endured last year's wintry blast to eventually play Oklahoma City Bishop McGuinness in the finals.
The Irish rolled to a 31-0 victory to claim the title.
Glenpool opened post-season play with a 40-0 drubbing of Guymon last Friday.
The Ridgerunners did the bulk of their damage in a 23-0 win over Hilldale in the third quarter last Friday.
And two of the scores came on runbacks - Dusty Gehrke had a 63-yard punt return in the first quarter and an 86-yard return of an interception by Cory Davenport as time expired in the first half.
Grove also recovered a fumble to set up a 20-yard run by Darrius Hopper.
The Ridgerunners' only points of the second half came on a 27-yard field goal by T.J. Griffith.
