Following a 7-4 loss to Boston on Sunday night, Chicago is 3-15 against left-handed starters. Cubs hitters began the day batting .224 against southpaws, third lowest in the National League.
"It's almost a fluke," Cubs manager Dale Sveum said. "Coming into the season, I thought that would be one of our strong points."
He thought that because of players like Jeff Baker, who batted .314 against lefties last season but is hitting .244 this year.
"It's not that they're doing horrible, but we're not getting the slugging percentage at all against left-handed pitching which is holding us back from scoring multiple runs in an inning," Sveum said.
On Saturday against Boston lefty Jon Lester, the only player to do damage was the only lefty in the lineup, Luis Valbuena, who hit a three-run homer.
Has Sveum considered using more lefties against lefties?
"Our left-handers aren't doing anything on a consistent basis to warrant that," Sveum said. "We're getting our hits, we're just not scoring runs."
