Former Red Sox infielder Jose Offerman was arrested Tuesday night after charging the mound and hitting the pitcher and catcher with his bat during an independent minor league game. He was charged with two counts of second-degree assault, and posted $10,000 bond. Offerman is due in Bridgeport Superior Court on Aug. 23, court officials said Wednesday. Offerman, playing for the Long Island Ducks in the Atlantic League, homered in the first inning. The next inning, he was hit by a pitch from Bridgeport Blue Fish starter Matt Beech and charged the mound with his bat. Offerman hit Beech in the hands and struck catcher John Nathans in the head. The Connecticut Post reported that Nathans suffered from nausea, Bluefish lefthander Mike Porzio said. Police said Beech, according to the Post, had a broken right middle finger.
