The American umpiring crew involved in Jose Offerman's latest on-field meltdown resigned within hours from the Dominican Winter League and has already left the country.

Daniel Rayburn, the target of Licey manager Offerman's thrown punch during a heated argument in Saturday night's game, was one of the four umpires to leave the Dominican Republic after filing reports of the incident.

Jayson Bradley, Justin Vogel and Barry Larson also tendered their resignations to the Dominican League and departed out of fear for their safety.

ESPN.com first reported the development, citing a source which said that the umpiring quartet "left after filing their report of Saturday's incident."

Offerman was arrested and spent two hours in a police station near Quisqueya Stadium after taking a swing at Rayburn during an argument begun when the former Major Leaguer went on the field to object to the ejection of Ronny Paulino by plate umpire Bradley.

At the conclusion of the game between Licey and Cibao, fans reportedly subjected the departing umpires to threats.

The president of the Dominican League expressed regret for the incident.

"It's unheard of that passion in sports reaches levels on intolerance and violence in professional sports as exhibited by a successful athlete, who many Dominicans admire and love," said Leonardo Matos-Berrido. "The Dominican League, its associates and executives offer our national fans and all the Dominican people, who strongly support baseball, our excuses (sic) for this regrettable event."

Offerman still faces battery charges if Rayburn files charges against him.
