Ruthless Kyle Edmund in cruise control at Grand Prix
Top seed Albert Ramos-Vinolas and the second-seeded Kyle Edmund made comfortable progress in the opening round of the Grand Prix Hassan II.
Spaniard Ramos-Vinolas faced few problems as he saw off home hope Amine Ahouda 6-1 6-2 in Marrakech.
British No.1 Edmund raced into a 5-0 lead against Jiri Vesely and what was already shaping up to be a routine win for the 23-year-old became even easier when Vesely retired from the match.
It was not all plain sailing for the seeds though.
Holland's Robin Haase, the fifth seed, went down 4-6 6-4 7-5 to Mirza Basic of Bosnia and Alexandr Dolgopolov, the seventh seed from Ukraine, lost 6-2 6-3 to Italian Andrea Arnaboldi.
Having elected to receive, Edmund quickly got his powerful forehand working and broke his opponent's serve in the opening game.
Edmund did not drop a point in the next two games and lost only his third point of the match when he double faulted in game four for 15-15.
But after winning the next three points, Edmund held a 4-0 lead. He looked set to take game five after going 40-0 up only for rival Vesely to bring it back to deuce.
Edmund won the next point to earn a fourth break point of the game and made no mistake to claim a 5-0 lead in the opening set, at which point Vesely retired to hand his opponent an easy win.
In the next round, Edmund will meet Italy's Andreas Seppi or Radu Albot of Moldova.
