The world's top two golfers, Luke Donald and Rory McIlroy, have been paired together in the first two rounds at the Memorial tournament at Muirfield Village in Ohio.
Donald and McIlroy have traded the world's top spot on multiple occasions in the last year, with Donald currently on top after his triumph at Wentworth on Sunday.
McIlroy is in contrasting form having missed his last two cuts, and will be hoping for improved form this weekend ahead of the upcoming US Open where he will be defending his title.
The duo could swap places again if McIlroy wins and Donald finishes outside the top 13.
