Cycling-Greipel wins Giro's stage two and takes overall lead

May 6 ( Reuters) - German Andre Greipel took his seventh win on the Giro d'Italia when he claimed the second stage in a bunch sprint finish on Saturday.

The Lotto Soudal rider passed Australian Caleb Ewan, whose chances were ruined when his left shoe came off its clip, and never looked back as he also snatched the overall leader's pink jersey.

Italian Roberto Ferrari ( UAE Team Emirates) took second place ahead of Belgian Jasper Stuyven ( Trek Segafredo) at the end of an undulating, 221-km stage between Olbia and Tortoli in Sardinia.

"There was no trouble with Caleb's bike. He collided with another rider and it caused the incident and ruined his sprint," said Ewan's sports director at Orica-Scott, Matt White.

"It was not an easy day, six hours on the bike. I owe it to my team mates who worked hard all day," said Greipel, who is leading a grand tour for the first time in his career.
