Frederick starter Zachery Kerr pitched the Keys' second shutout in a row at Prince William County Stadium last night to hand the Cannons a 2-0, season-ending loss in front of 3,331.
Kerr (14-7) went seven innings, yielding four hits, striking out six and walking none. After yielding singles in the first three innings, Kerr (3.06 ERA) did not yield another hit until the seventh.
He was relieved by Todd Stephan, who earned his 17th save.
Cannons right-hander Frank Seminara came up the loser by giving up two runs on six hits in 7 2/3 innings.
In both the fourth and fifth innings, Frederick's leadoff batter scored.
Tyrone Kingwood led off the fourth with a walk, stole second and came home on Pete Rose's single to right-center to score the first run.
In the fifth, leadoff batter Mike Lehman singled and advanced on a groundout and a wild pitch before Kingwood doubled for 2-0.
Prince William (29-37) won't defend its Carolina League crown as Frederick (33-29) hosts Salem in a four-game series that starts today before representing the Northern Division in the Carolina League championship.
The Keys may be without Mike Oquist, who pitched an 8-0 shutout Wednesday, then was given leave after learning of his father's death.
