Hughes has accepted a job as the high performance manager of Baseball WA and will work with the elite junior players and help out coaching their on-field performance.
The Heat, based at Baseball Park in Thornlie, finished fifth on the ladder and as a result missed out on playing finals.
The Perth-based side has been the most successful team since the league was re-vamped in 2009, being champions four out of six seasons and coming second once.
Starting locally at the Morley Eagles, Hughes has climbed the ladder of baseball, all the way to the highest level with the Minnesota Twins and Oakland Athletics, where his first home run in his first Major League game will forever live in Australian baseball folklore.
The 31-year-old said now he was no longer playing overseas, he wanted to start thinking about his coaching career.
“I am pretty excited to move into this new role,” he said.
“My job is to help guide the junior baseball players, both men and women, over the next couple of months,” he said.
“We have a strong program here in WA.”
Hughes said he was disappointed not to make finals with the Heat in the 2015-16 ABL season, but the side would be back.
“We have had a lot of success of the last eight years. Moving forward, we want to be more consistent for the full season,” he said.
