The Australian outfit, which made its race debut last year, picked up their first Tour de France stage win thanks to Gerrans when he pipped Peter Sagan at the finish line in Calvi on Monday.
Orica’s triumphant ride over a mainly flat course around Nice pushed Omega-Pharma off the virtual leaderboard by just one second.
Gerrans now leads teammate Daryl Impey by one second in the general classification ahead of today’s fifth stage.
“We weren’t the favourites for this course but we went out and gave it everything we had,” said Gerrans.
Hard work pays
“On this team we’re all good friends and we work hard to help each other. It’s been a dream two days for us. It really doesn’t get any better than this.”
Despite having no yellow jersey contender in their team Orica-GreenEdge were overjoyed at a prestigious collective win which means Gerrans will wear yellow into today’s stage from Cagnes-sur-Mer to Marseille. With no time bonuses, he could also realistically keep the race lead till Saturday.
