LOMOND lost their third home game in a row after Milton's smash and grab.
The home side had most of the play but could not convert pressure into goals as Milton's only shot on target won them the match.
That came from the penalty spot with just 15 minutes left after stand-in goalkeeper Fraser Thomson upended the visitors number eight in the box.
A red card followed for Thomson despite the striker having knocked the ball out of play and Lomond having a defender in line with the incident.
Lomond felt aggrieved at the referee's decision, especially given that a Milton midfielder escaped with just a yellow for a stamp in the first half.
After a scrappy opening 15 minutes Lomond emerged as the more dominant side but despite getting behind the defence on numerous occasions, the final ball let them down.
That story continued into the second half although David Elder was inches away with two long range efforts.
Alan Reid saw a chip beat the keeper on 65 minutes, but a defender headed the ball off the line.
Milton were pinned back and defending resolutely but won the penalty on a rare foray into the Lomond box, following a poor kick-out by Thomson.
Despite down to 10 men, Lomond remained the more dominant side but despite giving everything, there was to be no equaliser.
