Cubs left-hander Jon Lester laid down the gauntlet for his team come later this month after pitching in his regular-season finale Saturday:

Some 100-plus wins are nice, but they'll mean little if October doesn't go the Cubs' way.

"This season isn't anything unless we do what we showed up at spring training to do -- win a World Series," Lester said after failing to win his 20th game in a 7-4 loss to the Reds. "I don't want to sound like an a--h--- or anything, but we really haven't done anything yet."
