Adrian Mannarino eased past Taylor Fritz 6-3 6-2 in the first round of the Nottingham Open, while Daniel Evans saved three match points against Liam Broady in order to advance.
American Fritz took Roger Federer to three sets in Stuttgart this month but failed to produce a display of similar steel against Mannarino.
The Frenchman secured two breaks in each set to see out the match in under an hour and set up a second-round clash with 12th seed Paolo Lorenzi.
Evans lost his first set to wildcard and world number 234 Broady but battled back to see out a 3-6 6-2 7-6 (8-6) triumph - the final set lasting 60 minutes.
Evgeny Donskoy will meet Marcos Baghdatis in the next round after easing past Denis Kudla 6-4 6-4, while Mikhail Youzhny and Teymuraz Gabashvili was suspended following rain.
Gabashvili holds a one-set lead with play to resume on Monday at 6-4 3-3, with Youzhny serving at 15-15.
