Vijay Singh and Rory Sabbatini have well-earned reputations as two of the surliest members of the PGA Tour, so it was only a matter of time before they clashed. At the Sony Open, Sabbatini was paired with Singh, who reportedly became incensed with Sabbatini's caddie after a blown par putt, and a profanity-laced argument soon followed. Check out the following incidents and feuds from the eventful careers of Vijay and Sabbo.

Vijay vs. Tiger At the 2000 Presidents Cup, Singh and Reteif Goosen defeated Tiger Woods and Notah Begay III in Saturday four-balls. The next day, Vijay's caddie wore a hat with "Tiger Who?" on the back. Unfortunately for him, Vijay faced Tiger in singles that day, and Tiger trounced him, 2 and 1.

Vijay vs. Annika In 2003, Annika Sorenstam made her PGA Tour debut at the Colonial. Singh was not happy about the LPGA legend playing on the "men's" tour, saying, "I hope she misses the cut... Why? Because she doesn't belong out here.'' He went on to threaten to withdraw from the tournament if he was paired with Sorenstam.

Vijay vs. Phil After a round at the 2005 Masters, Singh confronted Phil Mickelson in the locker room and argued that Phil's metal spikes had roughed up the greens. They reportedly had to be separated by onlookers. Ironically, the two were paired together in the final round (pictured).

Sabbo vs. Crane Sabbatini and Ben Crane, a notoriously slow player, were paired together in the final round of the 2005 Booz Allen Classic. Frustrated with the pace of play, Sabbatini putted out of turn at the 17th and then stormed off to the 18th tee before Crane was able to finish the hole. The crowds at Congressional showered Sabbo with boos, and he later publicly apologized to Ben Crane and the Tour.

Sabbo vs. Tiger After the 2007 Wachovia Championship, in which Sabbatini and Tiger played together on Sunday, Sabbatini told the media that Tiger was "more beatable than ever" despite the fact that Woods had actually won the tournament. Shortly thereafter, Woods came from well behind 54-hole leader Sabbatini to win the WGC-Bridgestone.

Sabbo vs. O'Hair In 2011, Sabbatini got into not one but two separate altercations with Tour nice-guy Sean O'Hair. First, Sabbo began cursing and yelling at a 16-year-old volunteer at the Northern Trust Open who was helping him look for his ball, and O'Hair intervened. Not long after, Sabbatini and O'Hair almost came to blows during a round at the Zurich Classic.
