Magdalena Frech's career-best season hit new heights with triumph at the WTA 500 Guadalajara Open AKRON on Sunday.

Frech, the No.5 seed from Poland, grabbed the first Hologic WTA Tour singles title of her career with a 7-6(5), 6-4 win over Australian qualifier Olivia Gadecki in the championship match in Mexico.

On Sunday evening, World No.43 Frech needed just under two hours to seal victory over 152nd-ranked Gadecki, who had never made a WTA singles quarterfinal before this week, let alone a final.

Frech, though, had been steadily rising all summer. She made her first career WTA singles final on the clay courts of WTA 250 Prague in July, then made her first hard-court quarterfinal last month, also in Mexico, in Monterrey.

Must See

This week, Frech stormed into her first hard-court semifinal and final, and now she is a champion on tour for the first time. With the win, Frech is projected to make her Top 40 debut in the PIF WTA Singles Rankings on Monday.

"Australian Open fourth round, the final in Prague, and the title here, it's the most amazing year of my career for sure," Frech said after attaining her latest milestone. "I'm super proud about my achievements this year, it's really amazing.

"Hard work from the previous years is paying off right now, and I'm so glad about this. I will try to keep this momentum going."

Match moments: The finalists were very protective of their serves in Sunday’s first set. There were no service breaks in the opener, and no break points were generated between 2-1 and the decisive tiebreak.

Very little separated the players through 5-5 in the tiebreak, but on the next point, Gadecki sent a service return wide, giving Frech the first set point at 6-5. There, the Aussie misfired on a forehand, and Frech eked out the one-set lead after a grueling 73 minutes.

The floodgates immediately opened on return in the second set, with Gadecki earning the first break of the day for either player in the first game. But Frech chased every ball down as the set continued, getting level at 2-2, then clinching a break lead at 5-3 with a passing winner.

Serving for the title, Frech missed out on one match point, and she allowed Gadecki back on serve at 5-4. But the Pole quickly raced to triple championship point in the following game, and Frech found one more successful passing shot to wrap up the title.

"Everything was going so fast for me," Frech said. "Actually when I lost this game [with the first match point], I said to myself, 'It's now or never, it's your chance to win this match in two sets,' and it's going to be always tougher because she was playing really, really well."

Doubles comeback: Earlier on Sunday, No.3 seeds Anna Danilina and Irina Khromacheva notched a come-from-behind 2-6, 7-5, [10-7] victory over No.4 seeds Oksana Kalashnikova and Kamilla Rakhimova in the Guadalajara Open AKRON doubles final. 

Danilina and Khromacheva trailed by a set and a break as late as 6-2, 5-4, but they grinded out the second-set comeback and held on in the match-tiebreak for an 85-minute win.

It is the second team title for Danilina and Khromacheva, who won the Iasi title in July. They also paired up to make the US Open quarterfinals last week. Overall, it is Danilina's seventh career WTA doubles title, and the sixth for Khromacheva.
