London - Dutch rider Dylan Groenewegen won his third stage in five days at the Tour of Britain as Italy's Matteo Trentin moved into the overall lead on Wednesday.
Groenewegen, who also won the first and third stages, finished ahead of Britain's Matt Walls and Trentin after a sprint finish through Birkenhead Park in the Wirral.
Trentin's four-second time bonus for finishing third was enough to put the Mitchelton-Scott rider back into the leader's green jersey, three seconds ahead of Dutch rider Mathieu van der Poel with Belgium's Jasper De Buyst in third, 10 seconds back.
Thursday's sixth stage could decide the outcome of the race with a 14.4 kilometre time trial around Pershore offering plenty of scope for changes in the general classification.
