Volquez once called Blue Jays "crybabies", when they complained after he made 3 HBPs on Blue Jays players. Twice on Donaldson and once on Tulowitzki. Toronto fans do not like him very much after that.
Ventura has a history of line brawls and foul attitudes towards opposition players, including, but not limited to, swearing at players reaching their first base after a hit, hitting batters and then pouring some swear words at them, and arguing with the 1B coach after he lets a hit.
