Milos Raonic made waves on the court and on social media Sunday morning after defeating tennis legend Roger Federer in straight sets at the Brisbane International.

In doing so, Raonic became the only player born in the 1990s to beat the Swiss sensation twice, a fact made even sweeter considering Raonic's former coach, Croatia's Ivan Ljubicic, left him to join Federer's team for the 2016 season.

Fans (and celebs) were pumped to wake up to such good news and quickly showed their support.

In true Twitter fashion, the tennis player's accessory made its way to the forefront forcing people to #believeinthesleeve.

Zac Efron's fan club got in on the action.

The sleeve even inspired some poetry.

But no one seemed more excited and supportive than his girlfriend, Canadian model Danielle Knudson.

Nothing wrong with a little pride, right Raonic?
