Offerman, manager of the Licey Tigers, appeared to hit first base umpire Daniel Rayburn in the face or neck with his fist during a heated discussion in a game against the Cibao Giants. Rayburn fell to the ground.
Offerman was detained by stadium security and taken to a police station to wait until the end of the game to see if Rayburn would press charges.
The Giants were leading, 6-0, in the third inning of the final game of the Winter League round-robin playoffs when plate umpire Jason Bradley ejected catcher Ronny Paulino for arguing balls and strikes.
Offerman came on to the field to talk to Bradley but ended up arguing with Rayburn.
It was the latest violent outburst by Offerman, an All-Star infielder with the Los Angeles Dodgers in 1995 and Boston Red Sox in 1999.
On Aug. 14, 2007, he was batting for the Long Island Ducks against the Bridgeport Bluefish in an independent league game when pitcher Matt Beech hit him with a fastball. Offerman charged the mound with his bat and swung at least twice, striking Beech and Bluefish catcher John Nathans.
In February 2009, Nathans sued Offerman in U.S. District Court in Bridgeport, seeking $4.8 million in damages. Nathans said the attack left him with permanent, career-ending injuries.
Offerman last played in the big leagues in 2005 with the New York Mets. He batted .273 during his 15 seasons in the Majors.
