Baseball is not like hockey in that you only get a few good fights every season. It may be early in the season, but we've already had one!
The fight happened during the Rockies and Padres game when Nolan Arenado was up at bat and Padres Luis Perdomo threw a ball behind him. Arenado immediately charged at the Padres pitcher and threw a punch which led to a massive brawl on the field.
Nolan Arenado, German Marquez and Gerardo Parra all got ejected for their roles in the brawl for Colorado.
