It's a Dubai-Doha dud for Australian Open champion Sofia Kenin

The 21-year-old American lost to Elena Rybakina last Tuesday in Dubai; this Tuesday, she fell to another young hitter, Dayana Yastremska.

For the second consecutive week, Australian Open champion Sofia Kenin has failed to advance past the opening round of a tournament. On Tuesday, the No. 6 seed at the Qatar Total Open in Doha fell to 25th-ranked—but unseeded—Dayana Yastremska, 6-3, 7-6 (4).

Kenin, who made her Top 5 debut in the WTA rankings this week, was looking to reset after she squandered a one set-lead in a loss to eventual Dubai finalist Elena Rybakina a week ago.

“Yeah, I'm not happy. I'm really upset about this,” Kenin said in Dubai after the defeat. “I really thought I could have somehow turned it around. I felt like I had the match play, I had the confidence. It just didn't work out today. It's obviously really upsetting and disappointing at the moment.”

On this day, no one-set lead would be squandered. Having won the opening set in straightforward fashion, Yastremska fought back from a 3-0 deficit in the second to oust the American. While Kenin broke Yastremska with the Ukranian serving for the match at 5-4, the 19-year-old recovered to close out the match in one hour and 34 minutes. Yastremska won 54 percent of Kenin's second-serve points, breaking serve three times.

Yastremska, who won titles in Hua Hin and Strasbourg last season, awaits the winner of the match between Garbine Muguruza and Ajla Tomljanovic.

Kenin has now lost three consecutive matches, including a Fed Cup defeat to Jelena Ostapenko.

Earlier in the day, No. 8 seed Petra Kvitova rallied to prevail over Carla Suarez Navarro, 4-6, 6-3, 6-0. Also advancing was Aryna Sabalenka, who fended off Anett Kontaveit, 7-5, 2-6, 7-5.

Later, top seed Ashleigh Barty will meet Laura Siegemund in her first match since bowing out to Kenin in the Australian Open semifinal.
