(Reuters) - What loomed as a blockbuster bout between two four-times major champions ended up a technical knockout as Brooks Koepka floored Rory McIlroy on the way to a three-stroke victory at the WGC-St. Jude Invitational in Memphis on Sunday.
Koepka had McIlroy reeling with early blows in the final round and never eased up on his out-of-sorts rival at TPC Southwind as he underlined his world number one status.
