Broadhurst suffered a serious injury to his right hand during the second round of the 2000 Dubai Desert Classic, and was unable to compete for the remainder of that season.

Broadhurst's run of good form in 2006 enabled him to reach a career-high of 46th in the Official World Golf Rankings.

He holds the Open Championship record for the best scoring round (−9) in relation to par, set in 1990 and only equalled by Rory McIlroy in 2010.

In 2018 he won the Senior PGA Championship by shooting a bogey-free final round 63, including a 30-foot putt to save par on the 14th hole.
