SANFORD — Sophomore running back Peter Hegarty scored on runs of 6 yards and 1 yard to help lead Sanford to a 49-14 win over Massabesic in a regular-season finale at Cobb Stadium.

The game was rescheduled from Friday night because of a threat of violence.

Sanford led 28-0 by halftime. Quarterback Chase Eldridge started the scoring with a 9-yard keeper up the middle. Hegarty used his quickness to elude Massabesic defenders for his touchdowns. Eldridge completed the first-half scoring with an 11-yard pass to wide receiver John Morgan.

Sanford (4-4) opened the second half with a touchdown drive starting deep in its territory and ending with Nick Love’s 1-yard run.

The game was marred by penalties. Two pass interference penalties on Sanford helped Massabesic (1-7) drive to a first-and-goal at the 3. Running back Michael Risti scored from the 1 for Massabesic’s first touchdown.

Sanford went to its bench and continued scoring. Ed Michetti broke through the line, cut left and outran the defense 67 yards down the sideline for a touchdown. Alex Grondin added a 30-yard touchdown run to complete Sanford’s scoring.

Connor McGehee kicked seven extra points.

Massabesic reserve quarterback Trevor Walton passed 14 yards to Noah Gerry for the final touchdown.

The sixth-seeded Spartans will visit No. 3 South Portland in a Western Class A quarterfinal.

WATERVILLE 25, WINSLOW 21: Dalton Denis caught a 37-yard touchdown pass from Brian Bellows with 20.3 seconds left, giving the Purple Panthers (7-1) a dramatic win at Waterville.

Waterville’s heroics came 24 seconds after it appeared Winslow would pull out a come-from-behind win. Zach Guptill scored on a 7-yard run to give the Black Raiders (7-1) a 21-18 lead with 44.7 seconds to play.

Despite the loss, Winslow will be the No. 1 seed for the Eastern Class C playoffs. Waterville is the No. 2 seed, and each team has a first-round bye.

Waterville’s winning drive went 58 yards in two plays. On first down, Bellows connected with tight end Troy Gurski on a 21-yard screen pass. Bellows threw a pass that hit Denis in stride down the left sideline.

OAK HILL 33, LISBON 14: The Raiders (6-2) rushed for more than 300 yards as they clinched the No. 2 seed in the Western Class D playoffs with a win over the Greyhounds (6-2) at Wales.
