The Morton girls basketball team fought off a major challenge from Limestone Thursday to win the Class 3A Washington Sectional title.
Livingston had a game-leading 18 points with six rebounds, while Byrne supplied 14 points and a game-best eight boards as the Potters won their 17th game in a row.
Morton (29-4) defeated the Rockets for the third time this season in an all-Mid-Illini Conference final.
"The Mid-Illini was well-represented," MHS head coach Bob Becker said. "That is what a sectional final should be like. Two teams played their hearts out."
Each of Morton's four postseason victories have come against an opponent with at least 20 wins.
After Limestone took a 33-32 lead on its first possession of the fourth quarter, the victorious girls responded with eight straight points.
The Potters will become one of just eight teams left in 3A (after the completion of a pair of postponed contests Saturday).
Morton advanced to the Pontiac Super-sectional, where it will play Kankakee McNamara at 7:30 p.m. Monday with a berth in the Illinois High School Association state final at stake.
The Potters smashed the Fightin' Irish six years ago, 52-24, on the way to a fourth-place Class AA state finish, the best in the program's history.
