absolutely start with simply capping head to head matchups.
More importantly, find a book where you can get odds for each day of the event. In other words, 2 or 3 ball action.
Golf can be beaten, that's for sure. And i'll tell you briefly how i do it.
I suggest getting the shotlinx information from the pgatour website. This way, you have every possible stat you can think of. Now, after each day you can get all the updated stats. Each course is obviously different, and each course has different characteristics that make different stat categories weighted differently. As a former mini tour player, i've personally played many of the courses in the PGA Tour rotation. The point is, get to know each course that the Tour plays, and understand what characteristics give players an "advantage."
I like to bet Saturdays and Sundays action more so than Thursday and Friday.
That's because you can track your stats for half the tournament before you make your wager. Head to head matchups mean it's literally 1 on 1 action. SImply compare the stats that you've been tracking, and decipher which player is performing better in the categories you find to be the most important that week.
The reason why golf is beatable from a betting standpoint is simply because golfing odds are so skewed toward the "popular/known player. The biggest reason why i like to play head to head daily matchups is because literally anything can happen. Also, golf is a game where if you are swinging well for one day, you are likely to carry it on to the next. Same goes on the other side as well, where if you are playing poorly it's hard to turn it around the very next day. Proof of all of this is the yearly WGC Match Play Championship. Year after year, you see the so called "upsets" happen against the 1, 2, and 3 seeds. To the general public, these seem like big upsets. But in reality, this is simply golf.
And that's why golf is beatable from a betting standpoint. Far, far too many people simply bet the name player.
The very fastest way you can become sharp is to set your own lines. Set your lines from head to head matchups for each round. Look up the tee times, and when they are in twosomes, set odds. Do this for a YEAR, seriously. You will becomes sharp quick.
From there, you can go into picking overall winners for the tournament, to top 10's and top 25's.
But it all starts with tracking stats and getting to know each course. Good luck buddy, and i saw that you already posted in the thread that jonpistone2 and i share each week. I'm sure jonpistone2 will answer your question as well. He's a sharp guy that knows his golf numbers as well.
