Rory McIlroy has joined Tiger Woods in surpassing US$100 million in career earnings on the PGA Tour, becoming just the second player to do so.

The Northern Irishman reached the landmark during the Houston Open over the past weekend, where a four-way tie for fifth netted him more than US$300,000.

McIlroy, 35, has secured 28 victories out of 262 PGA Tour events since his debut in 2010.

Woods, now 49, crossed the US$100 million threshold in 2012 and has since accumulated US$120 million in prize money with 82 wins in 378 events. (Reuters)
