On Wednesday afternoon, Milford senior Shannon Smith threw a five-inning perfect game for a 15-0 win at home against Stoughton.

Thirteen of the 15 outs were strikeouts for Smith, but it was hardly the first perfect game she has thrown for the 9-0 Scarlet Hawks. In her career, Smith has pitched 21 no-hitters and five perfect games.

In the fall of her junior year, Smith committed to play softball at the University of Kentucky.

During her senior year, Smith is 9-0, having pitched every game for the Scarlet Hawks. She has allowed just five hits and one earned run in 57 innings, striking out 120. Coach Brian Macchi knows she is a special talent.

“The mentality she brings to the field in practice and games is unique,” said Macchi. “It’s an honor to coach her. She’s been a major contributor since freshman year.”

Smith, a two-year captain, didn’t hurt Stoughton just on the mound. She went 3 for 3 at the plate, with a double, a home run, and three RBIs.

“She’s been in the middle of our lineup since day one,” said the coach. “She batted fifth for us her freshman year, and since she’s batted third or fourth.”

Macchi also said Smith’s leadership has been invaluable for the younger players.

“She truly is a great role model for the program,” he said. “It’s good for the younger kids to see how she carries herself. It’s a scenario where you want the younger players to see her.”

Macchi has coached the program for eight years now, and says he hasn’t seen anyone like Smith.

“For me, it’s the first time having a player of this caliber,” he said. “She’s one of the best, in my mind, in the state.”
