While hard-pushed to call it a slump, it is easy to feel that Martin Kaymer has rather stood still in 2012. However, that feeling is undoubtedly down to the fact that the German's story has been one of almost non-stop success since his maiden European Tour victory in 2008. A winner no fewer than four times in 2010, including a first major triumph in the USPGA at Whistling Straits, Kaymer added two more last year - including a stunning triumph at the HSBC Champions event on the back of a closing 63 - as he briefly secured the World No.1 spot. But having tinkered with his swing to try and incorporate a draw into his game, the German appears to have surrendered some of his renowned consistency as he attempts to bed in the changes. He did manage to make the cut at Augusta for the first time in five attempts back in April and has certainly been solid if not spectacular since The Masters. A top-10 finish at Pebble Beach two years ago remains his stand-out US Open result and, while he might not be one of the most talked about names heading into the Olympic Club, the German remains a proven winner who cannot be discounted at the big events.
