STANDISH — Catlin Norton hit a three-run home run and Alexis Bogdanovich worked out of a bases-loaded jam in the seventh inning as South Portland ended Scarborough’s reign as Class A softball champion.

The Red Riots (18-1) beat Scarborough 5-2 Tuesday afternoon on Ward Field at St. Joseph’s College for the Western Class A championship.

South Portland, which had been shut out the last five times it played Scarborough, will play the Eastern Maine champion Saturday at 4 p.m. here for the state title.

With the game tied at 1, South Portland put two runners on with one out in the top of the fourth. Norton then sent the first pitch from Mo Hannan over the left field fence to put the Riots up 4-1. Amanda Linscott had an RBI single later in the inning.

Scarborough loaded the bases with two outs in the seventh and got an RBI single by Hannan. But Abby Rutt flied out deep to center fielder Erin Bogdanovich to end it.
