Joey Votto removed his helmet and exchanged words with Milwaukee catcher Erik Kratz during an at-bat in the third inning Thursday night, prompting the Brewers and host Reds to clear the benches.
Players milled around the field briefly, many of them joking with one another, before returning to the benches and bullpens.
Votto thought he'd drawn a walk on a 3-1 pitch from Junior Guerra and started toward first base, but plate umpire Roberto Ortiz called it a strike. Votto and Kratz traded words as the Reds first baseman got back in the box, prompting their teammates to take to the field. When play resumed, Votto flied out.
"It was just a little bit of a misunderstanding at the plate," Votto said after the Reds' 6-4 loss. "It was just two guys having words. It was really nothing."
Votto was ejected in Atlanta on Wednesday by plate umpire Carlos Torres for arguing a called third strike, his eighth career ejection.
