Holger Rune maintained his impressive form by beating Thiago Monteiro in straight sets to reach the second round of the Stockholm Open on Monday.

Rune was beaten by Marc-Andrea Huesler in the final of the last tournament he entered in Sofia following a quarter-final appearance in Metz.

The Danish teenager, who last week announced Patrick Mouratoglou had joined his team for the rest of this season, defeated Monteiro 7-5 6-2 on his debut in the Swedish capital.

Rune did not face a break point and won 86 per cent of points on his first serve as he booked a meeting with Cristian Garin.

Garin beat qualifier Jason Kubler 6-2 6-4, while Maxime Cressy and Aslan Karatsev advanced to the last 16 at the expense of Ilya Ivashka and Lukas Rosol respectively.

Richard Gasquet consigned Stan Wawrinka to an early exit at the European Open, coming from a set down to win 2-6 7-6 (7-4) 6-4 in a battle of two of the most experienced players on the circuit.

Fifth seed Dan Evans beat Tallon Griekspoor 6-3 6-4 in the first round in Antwerp, while his fellow Brit Jack Draper was an emphatic 6-1 6-2 winner against Jenson Brooksby of the United States.
