Price retired Wise on the next pitch, and as he was walking to the dugout, claimed that Hallion yelled at him to "throw the ball over the [expletive] plate," and added that he had done nothing to show up the umpire.
The incident escalated when Price's remarks were relayed to Hallion after the game. He said Price's body language indicated his unhappiness with the call and that all he said to the pitcher was, "Just throw the ball." He also told a pool reporter that Price was a "liar."
After the game Price and other Rays players, including Jeremy Hellickson and player rep Matt Moore, tweeted about the incident, which could be considered in violation of baseball's social media policy, which prohibits comments that "denigrate" an umpire.
MLB's policy is not to comment on ongoing investigations.
Price's tweets included, "Someone give me the definition of a coward please," and "Someone please give me the definition of accountability."
