His late-game heroics, as well as some tough fourth-quarter defense, helped Abington Friends defeat Friends' Central, 55-52, for the championship at a packed Haverford College.
"It was roller-coaster," said Mayfield, who scored a team-high 12 points. "We got off to a good start, and then we kind of hit the bottom a bit."
The game began at a fast pace and continued at a pretty frenetic rate for 32 minutes, with each squad moving the ball quickly in transition.
After an evenly played first half, the Kangaroos (19-6 overall) trailed by as many as 16 points.
Down by 12 entering the fourth quarter, Abington Friends outscored the Phoenix, 20-5, in the final eight minutes behind a tremendous performance on defense that stopped the Phoenix from finding a rhythm.
The two teams had met on Jan. 28, with Friends' Central (20-7) defeating Abington Friends, 76-64.
"It was a little taste of revenge, but at the same time, we just wanted to win a championship," Mayfield said.
"It's been a long time since my school put up a banner, so it's just a fun and joyous experience to put a banner up."
Friends' Central will be the third seed in next week's Pennsylvania Independent Schools tournament, and Abington Friends will be seeded eighth.
