With the Dodgers trailing, 1-0, in an eventual 2-1, 10-inning victory over the White Sox, Matt Treanor appeared to score on a sacrifice fly by Elian Herrera after White Sox catcher Tyler Flowers dropped the ball at home plate.
Moments later, Chicago appealed that Treanor left third base too early and third-base umpire Jerry Meals ruled him out, ending the inning.
Mattingly waited until the top of the seventh to come out and argue the ruling with Meals. The usually calm manager got very heated, moving near Meals' face, waving his hands in the air and pointing his finger.
Home-plate umpire Gary Darling came over and got in the middle of Mattingly and Meals to break up the argument. After a few minutes, Mattingly followed Darling down the third-base line to home plate and proceeded to get just as close to him as he did with Meals, arguing the entire way down the line.
Injured center fielder Matt Kemp argued that replays proved Treanor had tagged up. Mattingly said Meals said something to Kemp along the lines that he couldn't argue the play because he's on the disabled list and that prompted Mattingly to leave the dugout in anger.
"I really went out to protect Matt," Mattingly said. "I didn't go out there to argue the play."
Eventually being told by Meals that he was 100 percent sure of the call got Mattingly only further frustrated.
"I understand close calls and bang bang and you can't see things and trying to see that at fast speed is different than replay," said Mattingly, who added the replays showed Treanor's foot was on the bag for 40 clicks -- 1.3 seconds -- before taking off. "It's hard for me to believe you can overturn a run if you are not 100 percent sure you got it right."
The ejection was Mattingly's fourth this season and seventh as Dodgers manager. The sold-out crowd gave him a standing ovation as he left the field.
