Dodgers manager Don Mattingly and Matt Kemp were ejected in the top of the second inning on Thursday night against the Pirates.

The ejections set off a lengthy argument with home plate umpire Angel Campos.

Joe Blanton later ran toward Campos as he was walking off the field after being removed from the game.

"We came here having won the first three games of the series. We're not a frustrated team," Mattingly said. "We're not trying to cause any trouble. It's not like we've lost 10 of 11 and looking for a fight. We're here ready to play baseball. To have Matt taken out of the game is not right."

Kemp needed to be restrained, at different times, by Mattingly, teammate Shane Victorino, bench coach Trey Hillman and other umpires.

"This isn't about being mad," Mattingly said. "This is something that has to go above me. It needs to go to the league. We're in a pennant race, and I've got a guy who was second in the MVP (voting) last year, and you can't take him out of the game for cheering for a teammate. If we had gone out of control, that's different. This is just unacceptable behavior (by Campos)."
