Defending champion and world number two Rory McIlroy of Northern Ireland plays a tee shot during a practice round for the 90th Masters at firm and fast Augusta National

Rory McIlroy seeks a historic repeat victory starting Thursday at the 90th Masters, while world number one Scottie Scheffler and Bryson DeChambeau lead a host of challengers in firm and fast conditions.

Second-ranked McIlroy completed a career Grand Slam by capturing the green jacket at Augusta National last year, but only Jack Nicklaus, Nick Faldo and Tiger Woods have won back-to-back green jackets, Woods the most recent in 2001-2002.
