Tiger Woods has hired a swing consultant as he prepares to return to competition.

Woods announced Saturday on Twitter that Dallas-based Chris Como, a specialist in biomechanics of the golf swing, will be working and consulting with him. Woods did not identify Como as his swing coach.

Woods already has had three swing coaches and four swings during a career that already has brought him 14 majors among his 79 PGA Tour titles. He most recently worked with Sean Foley, whom he dismissed in August after three years and no majors. Woods last won a major in 2008 at the U.S. Open.

Woods is to return Dec. 4-7 at his Hero World Challenge, an 18-man field of top 50 players at Isleworth.
