Naomi Osaka and Elena Rybakina win, Ons Jabeur loses in Doha evening matches

Naomi Osaka's comeback continues. She advances to the third round of the Qatar TotalEnergies Open after a straight-set victory over Petra Martic. Osaka cruised through the first set playing the best tennis since she came back from maternity leave. She spent the second set trading service breaks with Martic which led to a challenging tiebreaker that had Osaka coming from behind. The final score was 6-3, 7-6 (11-9)

Meanwhile, Elena Rybakina once again is in top form as she rolls in straight sets over Lin Zhu, 6-2, 6-1. Rybakina's impressive serve carried her to win 86% of her first serve points and 67% of her second serve points. She broke Zhu four times.

Those hoping that Osaka would face off against her doubles partner from last week, Ons Jabeur, in the next round were disappointed that Jabeur lost her match to Lesia Tsurenko in straight sets.

What is happening with Ons Jabeur?

Something is going on with Jabeur, but it is not clear what it is. She was in control of the first set and let it slip away. Tsurenko won 6-3, 6-2. Jabeur looked upset and sometimes pained on the court. On one of the changeovers, while sitting on her chair, she was shaking her head apparently in disappointment over her level of play. Is it a physical or emotional issue?

It is really disheartening to watch Jabeur struggle. Her game is shifty and crafty and when she is at her best, she is fun to watch. Jabeur was not the only high ranked player to lose in Doha on Tuesday. Coco Gauff lost to Katerina Siniakova in straight sets. Proof once again that on any given day, women's tennis's best players can be beaten given the talent pool on the WTA Tour.
