Grant's picked up both the man of the match, his fourth of the season, and doubled up by also finishing first in the player ratings.
He polled 29.1% of the man of the match vote to take first place with midfielder Dean Marney coming second with a 21.8% share. Danny Ings, making his first start for the Clarets, came third with 16.9% of the vote.
Grant was again the winner in the player ratings. He scored a rating of 7.27 out of 10 and that was comfortably ahead of Michael Duff whose rating of 6.51 was enough to give him second place just ahead of Marney who was third with a rating of 6.49 out of 10.
That result gives Lee Grant six points towards the Clarets Mad Player of the Year. There are three points for Marney, two for Duff and one for Ings.
Those points don't affect the top three but the gap is beginning to close for third place. Marney is now just four points behind Marvin Bartley and Grant a further three points behind.
Jay Rodriguez continues to hold a four point lead over Kieran Trippier with Bartley, currently out of the team, a further nine points behind.
The next man of the match vote will get underway on Sunday following the league game against Cardiff City, and will be available within an hour of the final whistle.
