Juan Martin del Potro sparks further comeback rumors after practice session with Gabriela Sabatini

TENNIS CHANNEL LIVE: Del Potro first teased a 2023 comeback at the end of March.

Vamos, indeed. With three little words (and four emojis) posted to Twitter, Gabriela Sabatini set social media ablaze by revealing to the world that she and Juan Martin del Potro were on the practice courts this week.

Both players from their country to win their respective US Open singles titles, they won their crowns 29 years apart: Sabatini was victorious in 1990, while del Potro famously won in 2009 by beating Rafael Nadal and Roger Federer in the last two rounds.

Sabatini, who retired from tennis in 1996 but has stayed close to the game in the years since, was long-complimentary of her countryman. They even practiced together once before this year, in Miami.

"We said, ‘OK, let's go hit some balls.' We played together for an hour—and it felt like I played a five-hour match," del Potro said in an April interview with the Associated Press. "I was completely exhausted."

While Sabatini will be back on court later this month at the legends event at Roland Garros (she'll play doubles there with another Argentine, Gisela Dulko), all eyes are on whether or not del Potro will make a return to Grand Slam play, too.

The injury-plagued del Potro last played on the ATP Tour last February—a first-round loss to fellow Argentine Federico Delbonis in Buenos Aires after nearly two years on the sidelines, that had all the makings of a career farewell at the time. But he revealed in that aforementioned AP interview last month that he hoped to give it one last run at Flushing Meadows, the site of his most memorable, and greatest, career triumph, if his body would allow him to.

"My goal is to be ready to play an official match in the tournament," del Potro said. "I will work hard for the last time, maybe, in my career, and then you never know. God will decide if I'm ready or not."

Is training with Sabatini again a sign that del Potro's US Open dream is closer to being a reality? Only time will tell.
