Tempers flare as Rockies top Braves
The Rockies led 8-3 in the eighth when Dickerson fouled away a pitch and knocked off Laird's facemask.
"It was on a two-strike slider on a backswing that I hit Laird, but it was an accident and I think they know that," Dickerson said.
A stunned Laird was on the ground for several minutes before walking off the field under his own power and being replaced by Evan Gattis.
With his next pitch, Atlanta reliever David Carpenter hit Dickerson in the thigh and was ejected.
"I guess Carpenter thought it was on purpose," Dickerson said.
Rockies manager Walt Weiss bolted from the dugout and began yelling at Carpenter, as well as in the general direction of Gonzalez.
Weiss was held back by home plate umpire Jordan Baker before being ejected. When he returned to the dugout, Weiss smashed a bat against the wall.
"If you think a guy can foul a ball off and then at the same time hit the catcher on the backswing on purpose, you got no clue," Weiss said. "They made their decision. They made a bad choice."
Carpenter denied throwing at Dickerson.
"I tried to run a fastball in on him, it cut a little bit and caught him," he said. "Dickerson was looking at me and I thought, 'You just got hit, go to first base, that's all there is to it.' Get on with the next batter. I was surprised getting tossed out of the game there, I was preparing for the next hitter."
In the ninth, Rockies reliever Nick Masset hit Gattis in the hip with a pitch. Both Masset and Rockies bench coach Tom Runnells were immediately tossed.
Jhoulys Chacin (1-4) pitched seven scoreless innings for his first win of the season, backed by home runs from Charlie Blackmon and Justin Morneau.
Chacin, who missed the first month of the season with a right shoulder strain, struck out five and walked two. Rookie Tommy La Stella was the only Braves player to get a hit off him, singling in the second and doubling in the fifth.
"I didn't feel that good today," Chacin said. "I was just trying to make my pitches. I was keeping my pitches down and trying to get ahead and that's pretty much what I did. Any time you're throwing strikes, you're usually going to get good results."
