"We knew we had lost a bit of control in midfield but we controlled it better in the second half," said McKinstry.
"I'd say probably 70 percent of the game was for us so we're pleased with the result and what it means for the table."
McKinstry praised his young goalkeeper, Caleb Omondi for making his selection count.
He said Omondi, 20, has a bright career ahead of him. Though many teams are hesitant of playing young goal keepers, McKinstey said he picked him since he knows his talent and quality.
Omondi was deputising Kevin Omondi, who saw red in last month's Mashemeji derby against Leopards, which Gor won 1-0.
"That doesn't mean we can relax but today was good for him. He made some good saves. He saved one free kick and even towards the end, he managed the game well," said the Northern Irishman.
Seal head coach Juma Abdalla was satisfied with his team's performance.
The players, he said, just lost concentration after their opponents scored from the spot.
"But am happy with my players. They played a good game. We only need to work on a few things before the next game, against Tusker,"said Abdallah.
Gor Mahia play Shabana next week with McKinstry expecting a tough match from a team fighting to keep their KPL status.
