World number one Angelique Kerber beat Carla Suarez Navarro 7-6 (8/6) 6-1 to set up a repeat of the 2013 Abierto Monterrey final against Anastasia Pavlyuchenkova.
Kerber lost to the Russian Pavlyuchenkova four years ago in Mexico, but she delivered a real statement of intent against Suarez Navarro in her semi-final.
After a first set which lasted over an hour and was settled by a tense tie-break, Kerber needed only 20 minutes to rattle through the second set and reach the final.

"It's a completely new year and a new match," Kerber said on BT Sport 2 when asked about the prospect of avenging that 2013 defeat to Pavlyuchenkova on Sunday.
"I think it will be a great atmosphere out here, I will try to enjoy the final and win it of course."
Three-time winner Pavlyuchenkova booked her spot in the final with a 6-2 6-4 victory over Caroline Garcia.
The match lasted one hour and 28 minutes and Pavlyuchenkova needed treatment on her left thigh after the first set.
The 25-year-old has previously admitted to feeling fatigued after a long campaign in Indian Wells and Miami, but she stayed on course for a fourth Monterrey success.
In the Volvo Car Open in Charleston, Jelena Ostapenko ousted the final remaining seed, number 11 Mirjana Lucic-Baroni, 6-3 5-7 6-4 in the semi-finals.
Ostapenko will now face Daria Kasatkina, who beat Laura Siegemund 3-6 6-2 6-1.
