What Grand Slam event did Henri Kontinen and John Peers win in 2017?

Henri Kontinen and John Peers won the Australian Open men’s doubles title in 2017.

The Finnish-Australian team defeated American brothers Bob and Mike Bryan in the final. Kontinen and Peers won the match in straight sets, 7–5, 7–5, at Melbourne Park on January 28, 2017.

The victory was significant because it gave both players their first Grand Slam men’s doubles title. Kontinen became the first Finnish man to win an Australian Open tennis title, while Peers became an Australian Grand Slam champion in front of a home crowd.

The pair had already shown strong form together and continued to be one of the leading doubles teams on tour. Their 2017 triumph is sometimes confused with the Australian Open mixed doubles event, but the question refers specifically to the men’s doubles draw. The Grand Slam event was therefore the Australian Open, not Wimbledon, Roland-Garros, or the US Open.
