The 39-year-old has finished second on two occasions, but has never been able to cross the finishing post in first place.
However, having moved to America in a bid to improve his game, Westwood has turned his attention to claiming the title in Augusta.
"I'm playing as well as I've ever played. I'm hopeful that I can start winning more over here and start winning some Majors," he told Sky Sports News. "[Moving to America] will give me a better opportunity."
One of Westwood's second-placed finishes was achieved at The Masters in 2010.
