South Fremantle are on the lookout for a new coach after Paul Hasleby quit tonight.
Hasleby, who will see out the season, told the Bulldogs board, staff and players that it was time to look at other interests.
South Fremantle chief executive officer Stuart Kemp said Hasleby had always been committed to the club. "Paul has always put his heart and soul into the role and is a passionate South Fremantle person," Kemp said.
"Things haven't gone his way and it's been a disappointing year. However, the season has a long way to go and we are positive we can do some damage in the back half of the year."
Hasleby has guided the Bulldogs to 16 wins from 52 matches after taking the reins before the start of the 2012 season.
South Fremantle finished sixth in 2012, seventh in 2013 and are eighth on the WAFL ladder ahead of Saturday's clash with Claremont at Claremont Showground.
Perth are also chasing a new league coach after Damien McMahon was sacked last week.
