A two-out double in the seventh inning broke up a perfect game for sophomore right-hander Nick Delp, but host and No. 1 Calvert Hall held on for a 2-0 victory over No. 13 Archbishop Curley in the Maryland Interscholastic Athletic Association A Conference baseball playoffs Friday night.

Delp finished the one-hitter for the Cardinals, who will face No. 2 Gilman on Sunday at 5 p.m. at Ripken Stadium in Aberdeen.

Calvert Hall must beat the Greyhounds in two straight games to win the title, while Gilman — as the winner's bracket champion — needs to win only one.

Stephen Decatur 3, No. 9 Reservoir 1: Two days after a 6-5 regional semifinal win over two-time defending state champion J.M. Bennett, the visiting Gators fell to the Seahawks in the Class 3A East state regional championship game.

"The experience of having to travel out here twice isn't easy," Reservoir coach Adam Leader said. "We gained a lot of experience this year that can only help us in the future, so I'm really proud of these guys and the way they're handling this now."

Reservoir tied the game at 1 in the top of the fourth on an infield single by Tony Grabow.

But Stephen Decatur went back ahead with an RBI double and then tacked on an insurance run in the fifth.

"That's how its been all year. We're young, we don't have a whole lot of pop, and the runs come one or two. Against good teams we don't really have big innings," Stephen Decatur coach Rich Ferro said.

Reservoir stranded seven base runners in the game, leaving the bases loaded in the second inning and two on with one out in the sixth.
