This certainly isn't the first time we've seen two big leaguers yap at each other on the field, and it definitely won't be the last. But it may be the oldest.
What could they be upset about? Did Moyer rake his leaves onto Chipper's lawn? Did Chipper not record that penalty stroke on the 16th hole? Maybe they both missed their naps?
Funny story: Jones claimed Moyer was irate that the Braves were stealing signs, an act Chipper vehemently denied. According to Mark Bowman, Chipper called Moyer "paranoid" and "told a couple of Rockies he would discuss things with Moyer if he wanted to meet him in the hallway last night."
Moyer offered no comment. So there's that.
