Conlon spot-kick nets Mariners crucial win
Barry Conlon's second-half penalty earned Grimsby another vital three points in their fight to avoid relegation from the Football League as they beat Aldershot 1-0.
The on-loan Bradford striker coolly converted in the 82nd minute after Anthony Charles had handled.
Grimsby keeper Wayne Henderson had earlier pulled off two important first-half saves.
After only five minutes he stretched to tip over a shot from Justin Cochrane and then raced from his goal to deny Kirk Hudson, who had broken clear only for the keeper to get a hand to his attempted chip.
Grimsby exerted heavy pressure after the break and Peter Bore saw a tremendous right-footed shot from 20 yards rattle the crossbar.
The Mariners finally broke through when a Hegarty through ball was handled by Charles under pressure from Conlon. The striker nonchalantly chipped the spot-kick home past a diving Mikhael Jaimez-Ruiz.
