Video: Laver Cup reunites "brothers" Schwartzman, Isner and Opelka

The annual Laver Cup is now known for bringing players from different countries together, as they compete under the banner of "Team World" or Team Europe" in order to lift the prestigious trophy.

Argentine Diego Schwartzman made his debut at the event in 2018, where he played alongside American John Isner. The difference in height (Schwartzman is 5'7 and Isner is 6'10) made for some interesting photographs, with both men jokingly referring to each other as long-lost brothers.

This year's edition sees a third "brother" added to the mix, as American Reilly Opelka (who is 6'11) will also be joining the fray. During the opening ceremony, Schwartzman joked that not only had he reunited with his twin brother Isner, but they had discovered a third long lost brother in Opelka.
