Ross Gload and Jorge Nunez also hit their first home runs of the season for the Knights (10-5), who earned their first four-game sweep since May 2001.
Matt Ginter (1-0) entered the game in the sixth for the Knights, relieving starter Jon Adkins, and pitched three innings of scoreless relief to get the win. Edwin Almonte pitched the ninth to earn his International League-leading sixth save.
Later Tonight the Knights will start a two-game series against the Durham Bulls.
Chris Cosbey stroked a game-winning single with two outs in the bottom of the ninth inning to propel the Huntsville Stars past the Birmingham Barons, 7-6.
The Barons, who are 5-11 in the Southern League's Western Division, lost their fourth straight game overall and their sixth straight on the road after opening the year with back-to-back wins at Greenville, S.C.
Tetsu Yofu (0-1), who had pitched 9 1/3 scoreless innings entering the game, allowed a run and three hits in 1 2/3 innings to get the loss.
Left-hander Neal Cotts (3-0) will go to the mound for tonight's 7 p.m. series finale in an effort to try stopping the Barons' losing streak. Huntsville left-hander Luis Martinez, who is 2-0 with a 0.00 ERA, will oppose him.
The Winston-Salem Wart-hogs' bullpen, solid through the first dozen games of the season, laid an egg on Easter.
The result was yesterday's unsightly 8-7 setbacks in 10 innings to the Frederick Keys in front of 755 fans at Ernie Shore Field. Relievers Josh Fields and Scott Patten, who entered the game with a combined earned-run average of 2.45, gave up six runs on eight hits in the final two innings while facing 17 batters.
The Bullpen collapse came at the expense of a great pitching performance by Frankie Francisco. Francisco (0-1) went five innings giving up two runs (none earned) on three hits, while striking out six.
The Warthogs, getting two hits each from Yan, Rogowski, Daylan Holt and Mike Morse, raked five Keys pitchers for 12 hits. But they squandered scoring opportunities in the first, when Rogowski was picked off second, in the seventh when Eric Welsh failed to execute a sacrifice bunt, and in the eighth when Yan broke off third on a grounder and was retired for the first out of the inning.
The Warthogs begin a three game series on Monday against the Potomac Cannons. LHP Byeong An (1-1, 4.09) will start for the Warthogs; the Cannons send RHP Daylan Childress (0-3, 6.75) to the hill.
The Kannapolis Intimidators were postponed…
