As Morton got back to winning in a 2-0 resounding Championship triumph against struggling Hamilton at Cappielow, Grant Gillespie avenged his previous team by scoring the opening goal.
Just after the halfway point, Robbie Muirhead twice came close to breaking the score, but his first close-range shot was stopped and his second attempt went just over the crossbar.
Morton continued to dominate and were rewarded with an opener by former Accies midfielder Gillespie, nine minutes after the break, as he got on the end of Calvin Miller’s corner to tap home from close range at the far post.
Defender Alex King doubled the hosts’ lead after 66 minutes as he slotted the ball under goalkeeper Ryan Fulton for his third goal of the season in all competitions as they ended a six-match winless run to leave Hamilton second-bottom and three points from safety.
