Dapto Chiefs and Berkeley Eagles baseball clubs have been fined $500 each in the aftermath to last Saturday's all-in brawl in their final-round first-grade clash.On Thursday night, the Illawarra Baseball League's judiciary found both clubs guilty of bringing the game into disrepute over the benches-clearing melee in the seventh inning. The tribunal also effectively put both clubs on a 12-month good behaviour bond and if a similar incident takes place they face suspension from the competition. But with only a six-team competition - which includes newcomers Shoalhaven Mariners, who did not win a game this season - the viability of the league would struggle without either Eagles or Chiefs. Chiefs plan to appeal their fine, claiming under the IBL's constitution the maximum amount a club can be fined is $250. Eagles catcher Mick Shipp, who was ejected from last Saturday's game, was exonerated by the judiciary and is free to play in today's elimination semi-final against Northern Pirates at Dalton Park. Chiefs host Wests Cardinals in the other semi-final, with the winner advancing to the grand final.
