As benches started to clear, Cubs manager Lou Piniella asked home plate umpire Jim Wolf why he ejected Lilly.
"He threw at him," said Wolf who was miked for the ESPN broadcast.
"How do you know?" Piniella said.
"I knew he was going to do it," Wolf replied. "I was waiting for it."
Renteria quickly retaliated, hitting Cubs second baseman
Mike Fontenot in the face with his right hand as he slid into second
base on a successful stolen base attempt with the next hitter,
Andruw Jones, at the plate.
Jones grounded out against right-hander Carlos Marmol -- Lilly's
replacement -- to end the inning.
Lilly had a 2-0 count on Renteria when he threw up and in. The ball appeared to hit Renteria on the hand. He took a couple of steps toward the mound
before Wolf and Cubs catcher Michael Barrett
stepped in front of him to prevent a fight.
Both benches emptied, but no punches were thrown.
Chris Woodward pinch-hit for Renteria in the fourth. A contusion
on his left hand, the result of Lilly's fastball, caused Renteria
to leave the game. The Braves said X-rays taken at Turner Field
Renteria homered and drove in four runs on Saturday.
Asked during the broadcast of the game on Sunday night if the teams had been warned before the contest, Piniella said, "No warning whatsoever."
Lilly threw 10 pitches, striking out two. The Cubs used five more pitchers and actually took a 4-2 lead into the eighth inning before losing 5-4.
