Not that he makes it difficult to tell how he's feeling on the course, but a closer look at Tiger Woods' body language has revealed some interesting insights into the 37-year-old's game.
The Wall Street Journal set out to study Woods' golf course gestures and what they mean for his play. More than 220 shots from six tournaments were classified as "good" (down the fairway or near the pin), "OK" (in the first cut or on the green but not close to the hole) and "bad" (in the trees, bunkers, etc.).
With Woods competing in this weekend's PGA Championship and vying for his first major title since 2008, this primer should give fans a clue into Woods' thinking.
Below are some of the findings. For the entire study, see here.
How To Read Tiger Woods' Body Language Slideshow
'The Stare Down'
When Woods likes one of his approach shots he'll freeze up, hold his club at a 45 degree angle and eye the ball. Most of the time this means Woods hit a good shot, but if he starts talking to himself that can mean he is unhappy with his attempt.
'The Club Held High'
When Woods holds his club straight up after a shot, more often than not, he is not happy.
'The Vocal Commands'
Author Geoff Foster labels this the most noticeable sign of a bad shot. If Woods yells at the ball or screams expletives, he is usually not pleased.
'The Quick-Tee Snatch'
If Woods quickly picks up his tee after a drive that means he's confident in where the ball is going to fall. Most of the time this is a signal that Woods is satisfied with his shot.
'The Temper'
For the most part, when Woods slams his club, swings it or tosses it he is unhappy with his shot.
