It was almost too coincidental. A bank of lights in left field went out just as it became painfully obvious to the Prince William Cannons that they will not be defending their 1989 Carolina League championship in the 1990 playoffs.

The Frederick Keys all but took care of that as they swept a doubleheader from the Cannons last night, 4-2 and 6-2.

Starting the night Prince William was three games back with eight to play. The Cannons were hoping to take at least three games of this five-game, three-day series, and leave their fate in the hands of the Lynchburg Red Sox. This feat was made significantly more arduous when Sherman Obando, their cleanup batter, was sidelined with torn knee ligaments.

The heavy-hitting Keys outhit the Cannons, 26-17, in the two games. In the first game, Frederick went down in order only in the first inning. The Keys put the leadoff batter on base five of seven innings.

The Keys collected 13 hits, and only two starters, Pete Rose and Roy Gilbert, went hitless. Tony Beasley led the Keys with three hits while Mel Wearing, Tim Holland and Mike Lehman each had two. Holland hit his eighth home run of the year in the fourth inning.

Prince William didn't have a quiet night at the plate either. Russ Davis, Brad Ausmus and Paul Oster combined for six of the Cannons' nine hits and Mauricio Zazueta had both RBI. But clutch hitting was what the Cannons couldn't do. Of the eight runners they stranded, five were in scoring position.
