Rather dubiously known for his shady cheating incident at the 2019 Heroe World Challenge, Patrick Reed's accomplishments have been vastly overshadowed by his several alleged cheating scandals.
Sergio Garcia is known for losing his temper- on and off the course. His biggest downfall came when he racially abused Tiger Woods during a public feud. To add to that, he was disqualified after intentionally damaging 5 greens at the 2019 Saudi Intl.
Ian Poulter is notoriously dubbed to be one of the more obnoxious golfers of all time. He is known to work well under pressure, but sometimes when things don't go his way he is known to be grumpy and sour.
Vijay Singh might be a good golfer on course, but his cold demeanour and rude behaviour make him rather infamous. He refuses to be a part of interviews, and often times is known as the golfer who no one wants to caddy for.
Rory Sabbatini is arguably one of the most hated golfer of all time. He is infamous for walking in front of Ben Green while he was setting up for his putt. He was voted to be the least favourite playing partner on a poll given out to golfers.
