Thornton Academy sophomore pitcher Beck Edgerly worked around seven hits, allowing one run in five innings to help the Golden Trojans defeat defending Class A champion South Portland, 5-1, in a Class A baseball game on Tuesday at Wainwright Sports Complex in South Portland.

Edgerly struck out six and did not walk a batter. Josh Penney and Jeremiah Chessie each worked a scoreless inning of relief.

Thornton, which fell to South Portland in last season’s regional final, improved to 4-3. South Portland is 4-5.

“It’s a positive step,” said Thornton Coach Jason Lariviere. “We got out of some jams defensively. That was the key. Beck made some good pitches and got out of jams. We played well.”

Penney and Brayden Duane each had two hits and an RBI for Thornton and Cam Cyr also had two hits to pace a 10-hit attack. The Trojans led 3-0 on three unearned runs as South Portland made three costly errors in the first two innings.

The Red Riots only run came on a sacrifice fly by Cam Barrett to score Easton Healy who had led off the second with a single. Corbin Voisine and Kason Lewis each had two hits for South Portland, which left 10 runners on base.
