Sixth-placed Glenavon secured a third successive Premiership win by beating Institute at Mourneview Park.
Ciaran Caldwell scored with a close range header from Kevin Braniff's inviting left-wing cross on 33 minutes.
Institute's star performer, Robbie Hume, levelled with a superb low 15-yard shot into the bottom corner in added time at the end of the half.
Ciaran Martyn netted the winner when he slammed the ball home for his ninth goal of the season in the 55th minute.
Martyn was on hand to convert after Kris Lindsay headed on William Murphy's free-kick.
Caldwell, Martyn and Eoin Bradley all went close in the first half for the Lurgan Blues while Hume could have equalised in the second half but curled an effort onto the bar and rifled over when well placed.
Paul Kee's side are now without a victory in 13 outings.
