Del Potro watch is on after saying he'd return in event of winning World Cup at US Open

Juan Martin Del Potro promised a fan that he'll play at the 2023 US Open if his country Argentina win the World Cup.

They did it just a few hours ago and fans are already talking on social media about whether Del Potro will really do it. The Del Potro watch is officially on as tennis reporter Jose Morgado wrote on Twitter. The Argentine retired earlier this year in Buenos Aires with a match against Delbonis on clay.

He was spotted practising a couple of times and many wondered whether he would ever come back. A full comeback is unlikely but a send-off at the US Open, which is his lone grand slam won, would be fitting.
