Britain's Billy Harris is one win away from a first Grand Slam main draw appearance after a hard-fought victory in the second round of French Open qualifying.

The 29-year-old beat France's Manuel Guinard 6-3 3-6 7-6 (10-4) on the Paris clay.

World number 202 Harris is the only Briton left in either the men's or women's qualifying tournaments.

He will play 14th seed Valentin Vacherot of Monaco for a place in the main draw, which starts on Sunday.

Harris won his first match on the ATP Tour in November last year, having spent the start of his professional career driving to tournaments in a Ford Transit van to save money.

He is appearing in just his fourth Grand Slam qualifying contest.
