Britain's Jacob Fearnley extended his winning streak to 13 matches as he beat Corentin Moutet at the Stockholm Open.
The Scot was unranked just over a year ago but has risen inside the top 100 on the back of winning four Challenger titles in a row.
The 23-year-old, having taken a few weeks off, won two qualifying matches to reach the main draw of the ATP 250 event in Sweden.
He beat France's Moutet 6-2 7-6 (7-5) to set up a second-round meeting with Dutch seventh seed Tallon Griekspoor.
It is Fearnley's second ATP Tour-level victory, having won in the Wimbledon first round in July after being given a wildcard.
