Joe Maddon wasn't happy with plate umpire D.J. Reyburn's strike zone in the Chicago Cubs' 6-5 win over the St. Louis Cardinals on Wednesday.

Maddon let Reyburn know his thoughts on the field before being ejected in the sixth inning and continued his criticism after the game.

"It was egregiously bad," Maddon said. "You cannot permit that to happen. We're trying to ascend and we're not going to take that from anybody, anywhere at any time."

Maddon said he was especially not pleased with how Reyburn was treating his young players.

The Cubs start three rookies in the lineup on a regular basis.

"I'm not going to put up with anything," Maddon said. "I'm not. And I'm not going to allow our guys to get shortchanged based on the fact they have haven't been here a long time.

"We play a veteran club with a veteran battery against guys with barely two months in the big leagues; I'm not going to take it. Our guys deserve equal treatment, and I'm not going to take it."
