Simona Halep picked up where she had left off as she claimed the Prague Open title on her return to action six months after winning her last tournament in Dubai.
Top seed Halep extended her winning streak to nine matches on Sunday with a 6-2 7-5 victory over Elise Mertens, and admitted playing amid the WTA Tour's new coronavirus protocols had been testing.
The Romanian world number two told the WTA's official website: "It was really tough to get back to official matches after such a long break.
"The emotions after staying in the room for 10 days were not easy – but you know, I have to take the positives also, I was able to win the tournament which means a lot.
"I was a little worried at the beginning, but here we felt very safe and all the restrictions and rules were respected. We can do tournaments like this week, I feel it’s a big chance for us to participate again.
"It’s very different and a little stressful and we have to adjust ourselves, but the fact that everyone was good, these 10 days means that everything was really well done."
The 28-year-old did not have things all her own way after Belgian third seed Mertens broke early to take a 2-0 lead, but a run of seven successive games put her firmly back on track to complete a straight-sets win in an hour and 33 minutes, although not before allowing a 4-2 second-set lead to slip from her grasp.
In Lexington, Kentucky, American Jennifer Brady landed her maiden WTA title when she defeated Switzerland's Jil Teichmann in the final of the Top Seed Open.
World number 48 Brady took an hour and 42 minutes to see off her opponent 6-3 6-4 to win the tournament on home soil without dropping a single set.
She had to save five break points in the seventh game before going on to clinch the opening set and broke early in the second to pave the way for victory.
