The Spanish star reached the final in Doha but she lost to Petra Kvitova, however, there was no denying Muguruza in her second decider of the year after almost two-and-a-half hours in Mexico.
Bertens wins at Charleston
At the Charleston Open, Bertens claimed the biggest title of her career after seeing off fifth seed Julia Goerges 6-2 6-1.
Belgian 12th seed Bertens was forced to play back-to-back matches on Sunday after rain wreaked havoc on Saturday.
But Bertens was not overawed in her second match of the day – having upstaged Madison Keys in a gruelling three-set battle – as she accounted for Germany's Goerges in less than an hour to secure her maiden WTA Tour Premier-level trophy.
"It's just unbelievable. I think I cannot really realise it yet, but I'm just so happy and proud I think of myself," Bertens said.
