Isle of Man racer Mark Cavendish, of the team, sealed overall victory on the Tour of Qatar on Friday after winning the sixth and final stage on the Doha Corniche.
The 2011 world champion won the 116km ride from Sealine Beach to Doha in a sprint finish ahead of Yauheni Hutarovich of Belarus and Barry Markus of the Netherlands.
It was Cavendish's eighth win in total on the Tour of Qatar, and his fourth in as many days.
He finishes top of the overall standings ahead of Americans Brent Bookwalter and Taylor Phinney, who emerged with the jersey for the best young rider.
"I'm over the moon," said Cavendish, who also won the points jersey.
"We come here every year almost guaranteed an overall victory with Tom Boonen, but he's recovering from an injury. So it put a little bit of pressure on me and I was a bit nervous.
"But I'm really happy to get the win. The guys worked incredible here. They really looked after me so, so well here and delivered every single day.
"I am so happy and proud I can bring it home again for the team again."
No rider had ever previously won four consecutive stages on the Tour of Qatar.
Belgian Boonen, a four-time winner of the Tour, won four stages in 2007, but not in succession.
