Senior Nick Vermillion threw a complete game three-hit shutout, Wednesday afternoon, leading top-ranked Archbishop Spalding to a 9-0 MIAA A Conference rout of No. 15 St. Mary’s, at Spalding.

Vermillion threw 98 pitches and allowed just three hits. He walked two and struck out nine. He also contributed at the plate with two hits, a double, a run scored and an RBI.

Justin Caesar also had two hits, including a double, scoring twice and driving in one run. Evan Fochtman was the third Spalding player with two hits. He scored a run and had one RBI.

Spalding (18-5 overall) is now 12-4 in the MIAA A as it seeks to nail down a top-two playoff seed and a first-round bye. The Cavaliers are two games behind first-place Calvert Hall with two to play, including one head-to-head, and one game ahead of third-place Gilman.

St. Mary’s (16-9 overall) fell to 8-7 in the league. The Saints are currently in fifth-place with three games to play. They are 1-1/2 games up on both Archbishop Curley and John Carroll, who are tied for sixth, so they still have some work to do to clinch the post-season spot.
