Andy Green did little to conceal his feelings about the home-plate collision that knocked Austin Hedges out of Monday night's game, calling Anthony Rizzo's hit "a cheap shot."

Rizzo was attempting to score from third base on a lineout to center by Kris Bryant in the bottom of the sixth when he slammed into Hedges. Rizzo's left shoulder caught Hedges square in the right thigh and midsection and the San Diego Padres catcher fell over backward, holding onto the ball for an inning-ending double play.

Hedges left the game with a bruised thigh. He was replaced by Luis Torrens.

"I think you look at that play and it's a fairly egregious violation of the rule," Green said. "The rule exists to protect the catcher. The safety of the catcher is more in jeopardy now when you have the rule to protect you because you're not expecting to get hit when you give a guy a plate like that.

"That's a cheap shot. I'm not saying he's a dirty player at all -- nobody is saying that -- but he clearly deviated from his path to hit our catcher, took our catcher out. Rule exists to protect him. It's a disheartening play to see come about like that."
