• Quick-Step rider the first Colombian to win four stages in one Giro • Geraint Thomas withdraws from race having suffered following crash

Colombia’s Fernando Gaviria continued to take the Giro d’Italia by storm when he timed his sprint to perfection to win the 13th stage on Friday, taking his tally to four victories in the race.

The Quick Step-Floors rider came from nowhere at the end of the 167km stage from Reggio Emilia to Tortona to blast through a gap and cross the line first.

Gaviria, making his Grand Tour debut, also won the third, fifth and 12th stages and leads the points classification. He becomes the first Colombian to win four stages at the same Giro.

Dutchman Tom Dumoulin (Team Sunweb) retained the overall leader’s pink jersey after arriving safely in the peloton.

Earlier on Friday, Team Sky announced the withdrawal of Geraint Thomas from the Giro. The Welsh rider had been struggling with injuries since his crash on Sunday, which saw him slip out of general classification contention.

Thomas, co-leading Team Sky in a Grand Tour for the first time, suffered shoulder and knee damage when a stationary police motorbike caused a crash late on during stage nine. Thomas was second overall at the time of the incident but lost over five minutes and slipped further back in stages 11 and 12.

“I’ve been suffering since my crash on Sunday,” Thomas said. “I’ve had an issue with my shoulder which is manageable, but my knee has also been getting worse each day. Obviously it’s never nice to leave a race early, especially when it’s your main goal of the season, but I have to look at the bigger picture. I’d love to continue, but it would be a case of trying to survive each day rather than racing. I’ll turn my attention to the Tour de France now, and I want to arrive there with the same good form I started the Giro with.”
