(Staff photo by MIKE GEORGE) Post 312 Juniors finish strong NORTH ATTLEBORO - Two days after a complete-game dandy by Garret Briggs, the South Attleboro Junior Legion baseball team got another mound gem, this time out of Brett Mastropoll. Mastropoll fashioned a three-hitter, striking out 11 as South Attleboro swept a doubleheader against the Fall River Indians. South Attleboro earned a forfeit win in the first game, then won the nightcap at North Attleboro High School behind Mastropoll, 2-1. South Attleboro ends the regular season 11-5 and still has a chance to win its division, but needs Somerset to lose twice this upcoming week. Regardless, South Attleboro qualified for the playoffs in this, its inaugural season. Mastropoll was the story Saturday as he was perfect through the first three innings. However, Fall River used two hits and a walk to score its lone run and tie the game at 1-all. South Attleboro answered in the bottom of the inning with what proved to be the game-winning run as Mastropoll singled, moved to second on a botched pickoff attempt, then scored on a Derek Burns RBI single up the middle. Fall River threatened in the seventh after an infield single and two walks, but Mastropoll escaped the bases-loaded, no-out jam, getting two strikeouts and a nice play at first base by Ryan Santos.
