Women's world No. 1 Naomi Osaka has pulled out of Saturday's (April 27) semi-finals at the Porsche Tennis Grand Prix in Stuttgart after failing to recover from an abdominal injury she suffered in her quarter-final match. The hard-hitting Estonian started to turn the set in her favor, clinching a second consecutive service break with a backhand victor down the line to lead 3-1. "I think I played the best in the first set, and then it just kind of dipped a little bit, but instead of swinging freely I would say I was trying to be more consistent". "Overall, I was pretty good on the legs (to move around the court) today". "This was a really good boost for me, because it let me know that even though I am internalizing pain or feelings, I can still win matches".
Then, she stunned Donna Vekic in a match that lasted for two hours and 12 minutes.

The first 18 events on the WTA calendar were won by 18 different players.
Vondrousova, 19, raced out of the gates and won the first five games to take the first set.
Nishikori saved three break points in the sixth game but Medvedev turned the momentum in an instant in the 12th game. Big serving put her up 3-0 in the breaker, and a forehand victor brought her to 6-0, lining up six match points.
