Major League Baseball has fined umpire Tom Hallion and Tampa Bay Rays pitchers David Price, Jeremy Hellickson and Matt Moore an unspecified amount for their involvement in an incident during this past Sunday's game against the Chicago White Sox, sources familiar with the situation told ESPN.com.

Price accused Hallion of swearing at him in the seventh inning after the ace left-hander showed frustration on the mound in reaction to a pitch he thought the umpire had missed.

The dispute escalated, Price claimed, after Hallion told him to "throw the [expletive] ball over the plate."

After Price recounted the sequence of events following the game, Hallion denied cursing and called the reigning American League Cy Young Award winner a "liar" during an interview with a pool reporter.

MLB vice president Joe Torre dispensed his punishment after reviewing the incident with the assistance of Peter Woodfork, who oversees MLB umpires, and Joe Garagiola, who handles player discipline.
