When was the last time American Serena Williams made his professional appearance in a 23-seat Grand Slam championship trophy? When was Andreescu, Canada's first Grand Slam singles champion, last played on the Tour?

I believe that many fans have difficulty giving a definite answer to this. However, recently, two key figures in the tennis world have identified their own comeback nodes. Let's take a look!
Serena Williams: Wimbledon is back on the field this year
The last appearance was at Last Year's Wimbledon
Born in September 1981, Serena Williams will soon celebrate her 41st birthday, and the last time the American star played at Wimbledon, now that the world ranking has slipped to 246th, was last year.
In fact, in the entire 2021 season that has ended, Serena Williams has only played six races. She played a melbourne warm-up match during the Australian Open last year, withdrew from the semi-final against Barty before the match, and moved to the Australian Open to stop the women's singles final four against Naomi Osaka.
After Serena chose to return in the clay season, she came to Parma after the first round of rome, again lost to Soniakova in the second round, and after being defeated by Lebakina in the fourth round of the French Open, Serena airborne to warm Upton and suffered the first round of the trip.
There is no doubt that with age and various injuries, Serena williams has long been unable to participate in the entire season, and even the Grand Slam tournament she is selective.
Recently, Serena said that she will return to the field at Wimbledon this year, which means that the Americans will directly skip this year's clay season, so are you optimistic about her comeback?
Andreescu: Stuttgart made a comeback with a wild card this year
The last appearance was at Indian Wells last year
Andreescu, born in 2000, is undoubtedly younger than Serena Williams, but the Canadian is also in a stop-and-go phase, and the last time she competed was in Indian Wells, which was adjusted to October.
2019 was andreescu's season of fame, when she won the BNP Paribas Open, the Rogers Cup and the US Open, when she won the Grand Slam title for the first time by beating Serena Williams.
Just as everyone was expecting another rising star in women's tennis, various injuries were in front of Andreescu, making her have to quit various big and small events from time to time.
From the beginning of her first Grand Slam participation in 2017, she has only participated in nine Grand Slam tournaments in more than five years, except for the 2019 US Open, the remaining eight cumulative results have only achieved 5 wins and 7 losses (2020 Wimbledon was not held).
Of course, As a post-zero player, Andreescu still has a relatively long career, and I hope that she can get out of the injury problem as soon as possible.
Andreescu, who is now ranked 119th in the world, has just won the regular wild card in Stuttgart and is looking forward to her wonderful performance! (Source: House of Tennis Author: Barbie)
