CHICAGO - Lou Piniella waved goodbye Sunday, bowing as out the Cubs' manager and ending a career that spanned five decades after the Atlanta Braves routed Chicago 16-5.
The 66-year-old Piniella announced before the game that he leaving to be with his ailing mother. Third base coach Mike Quade was promoted to interim manager.
The disappointing Cubs weren't able to send Piniella out as a winner. Omar Infante and Jason Heyward each hit a pair of home runs, and the Braves scored 11 times in the last three innings to break away.
Piniella was in the dugout when the game was over, and he waved his hat to longtime Braves manager Bobby Cox across the field. Cox plans to retire after the season.
Piniella hugged Cubs third baseman Aramis Ramirez before heading down the dugout tunnel to the clubhouse.
After contemplating the decision for several days and discussing it with Cubs general manager Jim Hendry, Piniella decided to walk away from baseball after 48 years as a player, manager and executive.
The surprising announcement came in a team handout in the morning, and after Piniella had repeatedly insisted he would finish the season.
"My mom needs me home and that's where I'm going," Piniella said.
The loss left the Cubs at 51-74. Atlanta held its lead in the NL East.
