The Padres Radio account on Twitter asked followers whether the team should "retaliate" as the series continues at Wrigley Field, while a Chicago Tribune columnist wrote that Rizzo should be suspended over the play.
Rizzo was trying to score on a fly ball by Kris Bryant but collided with the Padres catcher.
Padres: C Austin Hedges left the game with a bruised right thigh following a collision with Rizzo on the play at the plate in the sixth. 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.
"That's something where baseball needs to consider how you handle situations like this after it occurs", Green said, via MLB.com. Any umpire who actually relayed that message to Rizzo must not have read Rule 7.13, which Major League Baseball changed in December of 2013 and has hereafter been called the "Buster Posey rule".
Cubs manager Joe Maddon has encouraged players to remain aggressive if they see the catcher in the lane to the plate. LF Kyle Schwarber left the game after fouling a ball off his right ankle.
"It's a fairly egregious violation of the rule", Green said, via MLB.com. "I don't know how long he's out for".
