The gelding was sent for a spell after the Dandy Patch and he resumed racing in January but one run in the gelding was back in the paddock.
Last Guy Standing was having his second start in his latest campaign at Mowbray last Friday night and he produced a top effort to win the Cleghorn Farm Stakes over 2200m.
"He goes pretty well but he's still very green," Maine said.
"He wouldn't go up to the mobile tonight - he just baulked at it - so he's going to be out of the draw now."
Despite the horse being put out of the draw in mobile events in the short term, Maine was ecstatic about the win, as the horse is owned Lisa, who also bred him.
"It's a well-deserved result for her (Lisa) because she does most of the work with him," the trainer said.
Last Guy Standing scored by four metres from Inner City with Odins Call Girl a half-head astern with the winner clocking a mile rate of 2m.05.5s.
