Potomac Cannons Manager Joe Cunningham appears to have found the key to success.

Cunningham has had his players wear batting practice jerseys for the past four games and each has ended in victory, including last night's 5-4 win over the Winston-Salem Warthogs in a Class A Carolina League game before 2,603 at Pfitzner Stadium.

"It's the first time we won four in a row and the first time we've swept," he said. "It's been a long season. We will be wearing these same comfortable black outfits tomorrow."

Luck worked in reverse fashion for the Warthogs, who committed four errors to bring their season total to 176. The Warthogs (17-29) have committed 30 errors in their last 10 games and hold solid possession of last place in the Southern Division.

Andy Bevins gave the Cannons a 1-0 lead in the first inning with an RBI single up the middle. The Warthogs responded with a run in the second and back-to-back home runs in the third to take a 3-1 lead.

The Cannons (20-24) rallied for four runs in the fifth inning. With two men on and one out, Bevins was hit by a pitch to load the bases. On the next pitch, Billy Deck chopped a two-run single over the first baseman to make the score 4-3. David Kim hit a sacrifice fly to tie the score and Luke Quaccia followed with an RBI double.

William Ortega extended his hitting streak to 16 games.

"He's been one of the most consistent guys on the team," Cunningham said of Ortega. "If we've got runners in scoring position, that's the guy you want up there."

NAVIGATORS 5, BAYSOX 4: Pinch hitter Derek Shumpert's RBI double in the eighth inning lifted Norwich over visiting Bowie in a Class AA Eastern League game.

Norwich blew an early 3-0 lead. Tim DeCinces got the Baysox going with a home run in the sixth. Bowie added three more in the seventh on a homer from Rick Short and a two-run double from Cesar Devarez. Nick Johnson tied the game for the Navigators with a two-out home run in the bottom of that inning.

KEYS 7, BLUE ROCKS 3: Third baseman Ivanon Coffie finished one hit shy of the cycle -- he lacked a single -- and drove in two runs as Frederick defeated host Wilmington in a Carolina League game.
