"We're just going to play ball," Baker said before Monday's game between the two teams. "If whoever wants to do something, that's their prerogative. They can do what they want to."
Garza will start on Tuesday against the Reds for the first time since taking issue with Johnny Cueto. Cueto was upset Cubs lead-off hitter David DeJesus was taking his time between pitches in a game in late May and threw a ball over his head. Both benches were warned.
"Hopefully he learns to grow the hell up," Garza said at the time. "Cueto should learn you don't go after guys' heads. Don't wake a sleeping dog and I think that's kind of immature on his part and totally uncalled for. He's lucky that retaliation isn't in our vocabulary here."
Baker said half-kidding that both parties should fight it out instead of engaging in a war of words and possible bean-balls.
"Just put them in a room, let them box and let it be over with," Baker said. "I always said this, let it be like hockey, let them fight, someone hits the ground and it's over with. I'm serious about that."
Garza didn't address the issue on Monday as he doesn't normally speak to the media the day before a scheduled start.
"It's up to him," Baker said. "He's the one that said it. ... As far as I'm concerned it's over. I know Johnny got fined for it."
Baker was asked if he spoke to Garza about the incident.
"I don't even know Garza," he responded.
