Sloane Stephens will take on Dominika Cibulkova in the final of the Abierto Mexicano Telcel after both players recorded straight sets victories on Friday.
Stephens needed just 54 minutes to reach her second final of the year when she thumped eighth seed Yanina Wickmayer 6-2, 6-0.
Cibulkova, meanwhile, overcame Christina McHale 6-3, 6-3 in the other semi-final.
Stephens set the pace early on in her match, gaining an early break to open up a 4-1 lead as her Belgian opponent’s play was plagued by unforced errors.
Neither player was particularly impressive on serve and three breaks followed, with Stephens winning the set on her fourth opportunity.
The second set, though, proved to be something of a procession, with Cibulkova only managing to win four points on her own serve.
“Obviously playing in the semifinals of any tournament is going to be tough,” Stephens told the WTA website after her victory.
“Fortunately today I played some really solid tennis and played really well. It was a good day for me.
“I’ve played a lot of matches this year already and got some of the confidence going, built up some momentum. I’m just trying to keep that going here in Acapulco.”
After the first five games went with serve, Cibulkova got her nose in front with a break of serve in the sixth game. Leading 4-2, the Slovakian player held her next two service games to win the first set.
Although the second ended with the same score, the manner in which it came about was completely different.
Cibulkova got a break of serve in the opening game, but McHale responded with a break of her own in the fourth game.
The American lost her serve in the next game to hand Cibulkova the advantage once more, and after McHale was broken again at the next opportunity, the result seemed a foregone conclusion.
Serving for the match at 5-2, Cibulkova was broken to hand McHale a reprieve, but another loss of the serve in the next game handed the Slovak player the victory.
