Arnie's Army descends on Orlando

ORLANDO, Florida - Arnold Palmer will loom large over the Bay Hill Club & Lodge this week as the tournament that bears the golfing great's name takes place for the first time since his death.

Defending champion Jason Day and world No 3 Rory McIlroy will headline the Arnold Palmer Invitational, which is expected to unfurl as a four-day celebration of the life of one of golf's most beloved figures.

Palmer, who died last September at 87, is widely credited with transforming golf during his glittering playing career, broadening the sport's appeal while building a worldwide legion of devoted fans known as Arnie's Army.
