There are several articles available for reading on the internet regarding Augusta National favoring left handed players. I am providing the link for one of those articles. However, if you google this statement: Is the masters golf course set up to favor left handed players?" you will find many other articles. In the article below Luke Donald among others says that following the revamping of the course to "Tiger Proof" it, the course is now set up to favor a left handed player. I know many on this forum have high regard for Luke so please take the time to read this article and any others you might find on Google.
And for what it's worth Adam Scott DOES NOT have the greatest caddy ever. He has a caddy. Period.
