NASCAR driver Denny Hamlin says he's been working with a well-known sports psychologist in an attempt to improve his attitude and outlook.
Hamlin has had a disappointing season this year after falling short in his bid to wrest the championship away from Jimmie Johnson. Many have speculated he's not been the same on or off the track since the week before last year's season finale.
Hamlin said Tuesday that team owner Joe Gibbs set him up with Bob Rotella, a noted psychologist who has worked with several PGA golfers over the year.
Hamlin says the things he's learned from Rotella would have made a difference last season.
