Columbus Crew earned a final-day victory over Toronto FC as the regular season comes to a close in Major League Soccer.
Both sides missed out on a post-season place and were left to play for pride in their last fixture of the campaign.
A quiet second half hampered by heavy rain was brought to life when Higuain was fouled in the penalty area on 61 minutes.
The Argentine striker lashed home the spot kick to win the match with his fifth goal of the season.
Crew held on in the closing stages to confirm a sixth-place finish in the Eastern Conference while Toronto finish with the worst record in the entire MLS, earning just 23 points from 34 matches.
