No. 11 Chesapeake-AA scored five runs in the bottom of the first and never looked back in Tuesday's Class 4A state semifinal at the University of Maryland's Shipley Field, rolling to a 9-1 victory over Urbana.

The Cougars (18-7) were led by senior shortstop Michael Marsh, who added insurance runs with two-run homers in the fourth and sixth innings.

Junior pitcher Jason Seitler was dominant again, allowing just three hits in a complete-game effort for Chesapeake.

The right-handed ace has anchored the Cougars' pitching staff all season.

Chesapeake will play in the Class 4A state final Friday at Ripken Stadium against Sherwood, which defeated Eleanor Roosevelt, 5-0.
