Former Stratford High School star Matt Wieters dropped an opposite-field double just inside the foul line for the go-ahead run in the eighth inning as the Orioles beat the Royals, 4-3, on Tuesday night.

“I was leaning it,” Wieters told reporters after the game. “And I was pretty excited when the umpire made the fair signal.”

Wieters was 2 for 4 with two doubles and three runs batted-in, boosting his average to .234 and giving him 18 RBI for the season.
