Jessica Pegula is relieved to find herself in the semifinals of the ongoing Miami Open 2023, and she has expressed that through a cheeky post on social media.This is Pegula's second consecutive appearance in the final four of the WTA 1000 in the Floridian city. However, things weren't easy for the World No. 3, who had to fight off match points before coming through.Pegula faced Russia’s Anastasia Potapova in the rain-affected quarterfinal in Miami. The match commenced almost four hours later than expected and witnessed multiple rain delays.The circumstances contributed to some scrappy play from both competitors as they exchanged as many as 15 breaks between them. The three-set thriller officially lasted two hours and 36 minutes, with the American stealing the win well past 1 am.After the match, Pegula hilariously joked about the struggles of high-octane late-night finishes. The player confessed that she struggled to raise her cramped-up arm to brush her hair.“POV it’s 2am. You just won 7-6 in the 3rd and your arm is cramping trying to brush through your hair,” the 29-year-old tweeted.Jessie Pegula@JLPegulaPOV it’s 2am you just won 7-6 in the 3rd and your arm is cramping trying to brush through your hair158380POV it’s 2am you just won 7-6 in the 3rd and your arm is cramping trying to brush through your hair https://t.co/GTV615DlA8The quarterfinals of the Miami Open was Pegula and Potapova’s second clash in March.
