South River starter Zack Morris informed his coach just before the start of Friday's game against No. 3 North County that his arm was sore and he would be unable to pitch.
Coach Ken Dunn sent right-hander Ryan Schoenbauer to the mound on short notice, but he had trouble finding the strike zone, and the host Knights took advantage and went on to beat the No. 8 Seahawks, 10-7, improving to 4-0.
Schoenbauer walked four batters, gave up three hits and allowed four runs in 1 1/3 innings. A single to Joey Decoursey in the first inning drove in two runs and Decoursey scored a third on a single by left fielder Josh Pfisterer, as all nine Knights batted in the opening inning.
David Kersey came on in relief in the second, and South River (1-3) rallied in the fourth to within 4-3, on runs by Nick Whiting, Morris and J.K. White. Two of those runs came on Jesse Holian's double when Knights starter Michael Bronakoski left an 0-2 pitch hanging over the plate.
"I kind of lost my control a little bit in that fourth inning," said Bronakoski, who was being observed by coaches from the University of Maryland. "But I have a good defense behind me in the field and they backed me up and got us out of the inning."
And then Dino Stevens, the Knights' usual third baseman who was playing his first game at catcher, broke the game open in the bottom of the fourth when he doubled to drive in two runs and crossed the plate on the same play.
"I rounded second and came a little off the bag," Stevens said. "And then they threw the ball back, it bounded off a glove into the outfield and I was on my way."
South River produced a single, three doubles and a triple in the final inning to score four runs and make the final score respectable.
