RORY McILROY'S return to the top of the world rankings drew the inevitable 'witty' tweet from Lee Westwood.
Not to McIlroy himself, of course.
The bitter-tweet banter that used fly between these two stopped when the 22-year-old 'unfollowed' Westwood and Chubby Chandler upon leaving the International Sports Management stable for Horizon last October.
Instead, Westwood tweeted Luke Donald after his fellow Englishman's 37th-place finish at the RBC Heritage on Sunday ceded No 1 to McIlroy.
"Not my best week. Getting used to leaving this place ranked No 2," Donald tweeted, in reference to the play-off defeat at Harbour Town last year, which denied him the top spot. "Nice week off now."
To which Westwood replied: "You're such a loser, Luke! You let me down!"
"Sorry Westy," Donald fired back. "I'll try extra-hard at Wentworth again!"
Of course, Donald knocked Westwood off the top of the world by beating him in sudden-death at last May's BMW PGA Championship.
Sometimes the most honest words are delivered in jest on Twitter, making it virtually irresistible to the average sports follower.
"No 1 again without touching a golf club ... I wish it was (always) that easy," tweeted McIlroy, whose followers on Twitter last week topped the one million mark for the first time.
