With Stewart Petrie’s side looking to secure a sixth successive top four finish, the 26-year-old has once again had a good season defensively as well as chipping in with goals against Clyde and Peterhead, taking his club tally to 13.
The ex-St Johnstone man arrived at Links Park, initially on loan from Forfar Athletic in March 2015 and penned a permanent deal the following season.
Petrie said: “This is a great achievement for Andrew, but comes as no real surprise.
"His attitude, application and incredible levels of consistency means he remains arguably one of the best left backs in the league and will undoubtedly go on to receive many more of these awards.
"He is exactly the calibre of player we want to attract and retain at the club.”
