Germany's Sophia Popov and American Ally Ewing advanced to the LPGA Match-Play championship match with semi-final triumphs Sunday.
Popov and Ewing were set to meet on Sunday afternoon in the final at Shadow Creek in Las Vegas.
Ewing, ranked 30th, defeated Thailand's 23rd-ranked Ariya Jutanugarn 3&2 in one semi-final while Popov, ranked 21st, edged China's 28th-ranked Feng Shanshan 1-up in the other.
Ewing, who never trailed, won her only LPGA title last October at Lake Oconee.
Ewing, 28, won the 11th and 12th with pars to seize a 3-up advantage and birdied the par-4 14th to go 4-up with four holes to play.
Ariya birdied to win the 15th but the American advanced when both parred the par-5 16th.
Popov parred the 12th and birdied the par-3 13th to square the match with Feng, who had not trailed to that point.
Feng made a bogey at the par-3 17th to give Popov the lead and the German advanced when both players birdied the par-5 18th.
