Shelton scored eight unanswered runs as the No. 3 Gaels beat No. 2 Law 10-6 in the first of two SCC semfinal games moments ago at Yale Field.
It's Shelton's second SCC final appearance. The Gaels beat Notre Dame-West Haven to win the conference title in 2000.
It was the third time Shelton beat the Law, the defending SCC champs, this season.
Mike Georgalas went 2-for-3 with three RBIs to lead the Gaels.
Top-seeded Amity will face No. 5 Xavier at 7 p.m. in the other semifinal matchup.
