Konerko snapped an 0-for-26 skid with an eighth-inning single and Pierzynski added a go-ahead two-run single in the inning to lead the streaking White Sox to their sixth straight victory, 5-3 over Toronto on Friday night.
"I'm ready to break into the Lou Gehrig speech right now," said Konerko, who felt lucky after a week of bad luck. "I've never really experienced bad luck in the big leagues or any where before. I've never had to swallow so many balls in the last week."
Pierzynski entered his at-bat 2-for-29 in his career in Toronto. He fell behind 0-2 against closer Miguel Batista before singling to left with two outs to give Chicago a 5-3 lead.
"He was like 1-for-Canada in his career. He came up with the hit at the right time. We've been having a lot clutch hits since Opening Day," Chicago manager Ozzie Guillen said. "Every day it's somebody different."
Orlando Hernandez (4-1) pitched seven strong innings to help the White Sox improve their major league-leading record to 22-7. Chicago's starters are 17-3 with a 2.79 ERA.
"The pitching has been incredible," Pierzynski said. "When a pitcher gives you seven innings, three runs, you're going to win a lot of games."
Hernandez allowed three runs on six hits, struck out four and walked three.
Dustin Hermanson finished for his fifth save.
Corey Koskie homered for the Blue Jays, who had won seven of their previous nine.
"They got a key hit, we didn't," Toronto catcher Gregg Zaun
Chicago's Tadahito Iguchi singled in the first, stole second and advanced to third on a grounder before scoring on catcher Zaun's passed ball. Chicago has held a lead in all 29 of its games, surpassing the record to start a season of 25 games by the 1955 Brooklyn Dodgers.
"That was a backbreaker," Walker said.
