Lee Westwood is widely regarded as one of the most consistent golfers on today's circuit, but few might know the secret behind his success.
Over the years, the 40-year-old has developed an individual style of golf swing; one that is very complex, but rich in reward, and something that has been mastered during endless hours of practice on the driving range.
The former world number one has won more than three dozen tournaments worldwide during his professional career on the European Tour and PGA Tour, and he has also represented Europe in eight Ryder Cup competitions.
Westwood's dependable form and constant presence in major events is thanks largely to his good ball-striking, which is the main reason behind his consistency from tee to green - the main strength of his all-round game.
In a recent feature by Golf Digest, Teaching Professional Dean Reinmuth analyses Westwood's golf swing closely, in an attempt to highlight the level of coordination needed to replicate such a strange style which is delivered with 'robotic consistency'.
"As I see it, you get leverage from your legs. They're the biggest power providers, but you have to get your upper body synced with them," reflected Westwood when describing his approach.
"It's just the way I've always swung it. It's something that's ingrained, and it's very difficult to change."
Westwood's swing was on show at the US Open at Merion last weekend, finishing the second major of the 2013 season in tied-15th place, and he returns to action at the Travelers Championship in Connecticut on Thursday.
