Rory McIlroy got a ribbing from pal Graeme McDowell as his new squeeze Caroline Wozniacki crashed to defeat in Toronto.

But the good news is that the Holywood star will now have her cheering him from behind the ropes in the US PGA this week according to a source who spoke with McIlroy’s father, Gerry.

McIlroy watched on TV in the clubhouse in Atlanta last night as the Danish world No 1 took on Italy’s Robert Vinci in the second round of the Rogers Cup.

He eventually left to play nine holes with G-Mac who used his phone to follow the scores and counted down to Wozza’s KO with shouts of “15-love, 30-love, 40-love….”

According to the National Post:

After losing the first set, Wozniacki took a four-game lead in the second. But Vinci would not quit. Down 5-1, Vinci worked the score back to 5-5 and then broke Wozniacki’s serve to go ahead 6-5. She then held serve to win the match. Often described as the best player on the Tour to have not won a Grand Slam, Wozniacki will remain the No. 1 player in the world. She has won five tournaments this year and has a commanding 2,290 points lead on Clijsters.

The Danish beauty eventually went down 6-4, 7-5 but is now expected to turn up at Atlanta Athletic Club to cheer for Rory in the season’s final major.
