The top seeds, they won the final 7-6, 1-6, (10-3) against defending champions Japan’s Shingo Kunieda and Gustavo Fernandez from Argentina after a match tie-break.
Gordon and Alfie made a remarkable recovery to take the opening set of the men’ doubles final, fighting back from 5-2 down and three set points down to take the opening set.
The Australian Open and US Open champions could not find their way back from 5-0 down in the second set, but they made a much better start to the deciding match tie-break, establishing a 7-1 lead before taking their unbeaten winning streak for 2020 to 16 matches and seven tournaments.
Gordon, for whom this victory brought a ninth Grand Slam doubles title partnering Alfie and a third Roland Garros doubles title after 2015 and 2016 wins with Kunieda, said: “I think the initial sense was of relief after quite an up-and-down match, a lot of twists and turns, and it was quite emotionally draining as well.
"It means a lot to us as a team, because it was the last Grand Slam that we hadn’t won, and we’re not sure how many more times we’re going to have the opportunity to win it together.
“It’s probably this tournament last year where we got home so disappointed with the way we were playing, so we took a different approach. We committed to spending more time together working on doubles, and I really think that’s showed at the end of last year and the whole of this year.”
The pair have now earned themselves a return to the top of the mens doubles world rankings.
