Also in 2008 he made his Bathurst Cup – the premier international real tennis competition between nations – debut for France, winning both of his matches in the third place playoff against the United States.

He entered the British Amateur for the first time in 2012, struggling through the first round against William Fortune, but cruising comfortably in the semi final against Robert Hird.

However, he received a walkover in the semi final after his opponent, Peter Wright had his racquets vandalised (Sarlangue was not considered a suspect).

Sarlangue entered the British Open qualifying for the first time later that year, winning through to the main draw but losing in the first round to Chris Chapman.

[7] In 2017, Sarlangue played his most recent British Amateur to date, beating Cambridge's Ed Kay in the final in five sets, but losing in the doubles again to Wright and Douglas.

Later in the year, he qualified through to the main draw of the Champions Trophy at the Royal Tennis Court, pushing him into the top 10 of the world rankings.

At that year's Bathurst Cup in Racquet Club of Chicago, Sarlangue helped his team reach the final against Great Britain, winning all but one of his matches.

When play resumed, Sarlangue continued his run of quarter final appearances at the French Open in 2022,[10] and took France to second place to Great Britain at the Bathurst Cup at Lord's.
