Rory McIlroy has won the 2016 Deutsche Bank Championship.

The four-time major winner enjoyed an excellent final round, carding a 6-under round of 65 to finish on 15-under overall.

In a tense final round battle, he fended off the challenge of England's Paul Casey, who ended up two shots behind on 13-under.

Incredibly, McIlroy had been 4-over par after three holes of the championship, before racing back into contention. 



It's McIlroy's first win on the PGA Tour in 2016, although his victory at the Dubai Duty Free Irish Open means he had tasted a victory on the European Tour. 

Adam Scott and 2016 PGA Championship winner Jimmy Walker finished in a tie for third on 11-under.

Like McIlroy, Scott also had a positive final round with a 65.

Graeme McDowell was not involved in the final two rounds of action, having missed the cut on 2-over par.
