Barbora Strycova won the sole main-draw match at the Qatar Open on Monday, beating wildcard Fatma Al Nabhani in straight sets.
Strycova required just 64 minutes to see off the world number 406 6-1 6-1 and book her place in the second round on a rainy day in Doha.
The Omani was unable to hold serve once as Strycova advanced in routine fashion to set up a clash with seventh seed Anastasija Sevastova or Anna Blinkova.
Blinkova got past Sam Stosur 7-6 (7-1) 3-6 6-4 despite 14 double faults in her qualifying match, while Ajla Tomljanovic and Karolina Muchova also booked a place in the main draw and will face Julia Goerges (9) and Caroline Wozniacki (6) respectively.
Alison Riske and Polona Hercog suffered defeats but advanced as lucky losers.
