French Open finalist Maja Chwalinska crashed to a shock Wimbledon first-round defeat against Thailand's Mananchaya Sawangkaew on Monday after suffering an injury on match point.
Just weeks after her fairytale run as a qualifier at Roland Garros, Chwalinska was unable to recapture her clay-court magic on the grass of the All England Club.
The Polish 20th seed, beaten by Mirra Andreeva in the French Open final, took the first set against Sawangkaew, but crumbled over the final two sets as the world number 164 clinched a memorable 2-6, 7-5, 6-2 victory.
Chwalinska said the tie began to slip away from her when she sustained an ankle injury in a failed attempt to convert a match point in the second set.
"I fell and I felt my ankle. I wanted to continue, but it definitely didn't help me later on," Chwalinska said.
"It's Wimbledon. I don't want to retire in Wimbledon. I got cramps everywhere. I don't take a huge risk on my health, it's gonna be okay.
"But, yeah, I think I would have many regrets if I would retire, so I just wanted to continue."
SABALENKA EASES INTO WIMBLEDON SECOND ROUND
Aryna Sabalenka cruised through her opening match, seeing off Serbian qualifier Teodora Kostovic in straight sets on Centre Court.
The world No 1, who could be challenged for the top ranking by Elena Rybakina over the coming fortnight, wrapped up a 6-2, 6-3 win after 65 minutes.
"For the first match, I felt pretty good, I rate myself eight out of 10," Sabalenka said.
The Belarusian will continue her bid for a maiden Wimbledon title against American McCartney Kessler in the second round on Wednesday.
Sabalenka has been inconsistent by her high standards in recent months and has not reached a final since winning the Miami Open in March.
