Leave the GOAT aloneSerena Williams comeback didn't go as expectedSerena Williams suffered a rare first-round defeat at Wimbledon.Serena Williams gave one of the biggest surprises to tennis fans a few days before the 2022 Wimbledon Championships by announcing her comeback at Eastbourne, where she played doubles with Ons Jabeur. She was subsequently awarded a singles wildcard for the grasscourt Major.However, the 23-time Grand Slam champion failed to advance to the second round as she lost to France's Harmony Tan in a little over three hours.This was the first singles match for the American in 52 weeks, with her last one coming against Aliaksandra Sasnovich of Belarus in the first round of the 2021 Wimbledon Championships. Williams suffered a leg injury and had to retire from that match, which kept her out of action for nearly a year after that.
