Australian Open 2017 finalist Rafael Nadal ran over Croatia's Marin Cilic 6-1, 6-2 to reach the Mexican Open final on Saturday.
In search of his first title this season and 70th on the whole, the 30-year-old Spaniard continued his Mexican Open winning run and took the tally to 14 matches and 28 sets.
He won the event in 2005 and 2013, when it was played on clay.
Nadal will be up against American Sam Querrey in the final who won 3-6, 6-1, 7-5 against Australia's youngster Nick Kyrgios.
The second-seeded Nadal last won a hard-court title in January 2014 in Doha.
He is playing his first tournament since losing to Roger Federer in the Australian Open final.
"You need to have a great day to get a result like this against Cilic," Nadal said. "Anytime you play against someone like Cilic, you expect to suffer in a tight match, but it was not like that. I believe that he had his chances, but I played a good game."
In the other semi-final, Querrey continued his great momentum after having defeated David Goffin and Dominic Thiem and beat Kyrgios who stunned World No. 2 Novak Djokovic on Thursday. Querrey had ended Thiem's seven-match winning streak.
"It does not get any easier tomorrow (Sunday); it will be the toughest test," Querrey said. "I played great today (Saturday), but I need to play even better tomorrow (Sunday) to beat Nadal."
The American will try to win his ninth title and first since Delray Beach in 2016.
According to head-to-head record, Nadal enjoys a 0-4 advantage against Querrey.
In the women's semi-finals, second-seed Kristina Mladenovic of France beat American Christina McHale 7-5, 4-6, 6-2, and the Ukraine's Lesya Tsurenko led top-seeded Mirjana Lucic-Baroni of Croatia 5-0 when Lucic-Baroni retired because of a stomach virus.
