Prince William pitchers Frank Seminara and Cullen Hartzog each threw shutouts against Lynchburg as the Cannons swept the Red Sox, 5-0 and 6-0, in last night's doubleheader to clinch second place for the Cannons in the first-half Carolina League Northern Division race, in front of 2,136 at Prince William County Stadium.

Seminara (10-3) chalked up his third win against Lynchburg this season and extended to 21 his streak of innings without allowing an earned run. He went into the sixth inning of the seven-inning game with a no-hitter, but it was spoiled by John Malzone's double.

But Seminara, with a 1.23 ERA, recovered and went the distance, giving up only two hits and two walks and striking out eight.

In the first game, the Cannons' Dave Silvestri doubled with one out in the first inning and stole third. J.T. Snow singled between second and third to score Silvestri for a 1-0 lead.

Snow and Silvestri executed a perfect hit-and-run to produce the second Cannons run in the third when Silvestri took off from first and scored off Snow's deep hit to right field.

Hartzog (3-4), not to be outdone by Seminara, pitched five innings of the nightcap, giving up four hits, no walks and striking out eight.

Again, the Cannons scored in the first when leadoff batter Paul Oster tripled before Silvestri knocked him in on a fielder's choice. Red Sox shortstop James Byrd threw home, but Oster beat the throw.
