Pittsburgh Pirates manager Clint Hurdle, center, and catcher Russell Martin, left, argue with home plate umpire Dan Iassogna in the fourth inning of an baseball game against the Atlanta Braves Monday, June 3, 2013 in Atlanta. Both Hurdle and Martin were ejected.

ATLANTA — A.J. Burnett kept falling behind in counts, and that eventually became a big problem for the Pittsburgh Pirates.

Burnett gave up three two-run homers, and manager Clint Hurdle and catcher Russell Martin were ejected during Pittsburgh’s 7-2 loss to the Atlanta Braves on Monday night.

Burnett (3-6) yielded a season-high six runs in five innings. He also allowed eight hits and walked three.

Brian McCann, Jason Heyward and Freddie Freeman each hit a two-run shot for Atlanta, and Kris Medlen pitched seven strong innings in his first win since April 9.

Burnett said he fell behind in too many counts, especially in the Braves’ four-run fifth.

“I was making pitches early but that last inning I wasn’t able to make pitches,” Burnett said. “I got behind hitters. That’s a good-swinging team and you can’t get behind them. Especially throwing cookies in there when you do get behind them.

“It was once of those nights where I wasn’t able to get ahead later in the game.”

The three homers allowed matched Burnett’s career high. He last allowed three homers in a 6-5 loss to Tampa Bay on May 16, 2011.

McCann connected for his seventh homer in the fourth. Chris Johnson then doubled and was at second when Medlen’s two-out at-bat featured a couple of testy exchanges between umpire Dan Iassogna and the Pirates.

Burnett complained about the ball one call to Medlen, and Iassogna stepped in front of the plate to warn the pitcher.

After the second ball was called, Martin apparently complained as he took a couple of steps toward the mound with his back to the umpire. Martin was then thrown out by Iassogna, and the catcher turned to protest.

Hurdle charged from the dugout to take over the argument and also was thrown out.

Martin said he cursed after the second ball but said the profanity was not directed at Iassogna.

“I was frustrated and I got up and that’s it,” Martin said. “That’s all that happened. That’s exactly what happened. And he threw me out for that.”

Martin said he thought the quick ejection was an emotional reaction by Iassogna. Hurdle said for Martin “to get tossed walking away from the umpire, never turning his head, never saying anything, was disappointing.”

Michael McKenry replaced Martin behind the plate.

Heyward and Freeman homered during a string of fourth straight hits to open the fifth.

Medlen (2-6) pitched seven solid innings for his first win since April 9, ending a career-worst, five-game skid over his previous nine starts.
