Rory McIlroy put the setback of the two-shot penalty he received on Thursday behind him as he posted 11 birdies in shooting a nine-under-par second-round 63 at the Abu Dhabi Championship on Friday.

McIlroy had been handed the sanction for improving his lie during the opening round and as a result finished day one on two under par, eight shots behind the leader, Italian Francesco Laporta.

The six-time major winner was penalised after pressing down on the grass behind his ball with his club before hitting a chip on the par-four 12th at Yas Links.

The Northern Ireland player responded in style in round two however to move to 11 under and assume the clubhouse lead with several of the leading players on the leaderboard still to complete their second 18 holes.

McIlroy began his round with a bogey at the first but bounced back by picking up shots at the second, fourth and seventh holes.

The back-to-back Masters champion then stormed up the leaderboard with five consecutive birdies from holes nine to 13.

A dropped shot at the 14th proved to be only a temporary blip as he recorded two further birdies on the 17th and 18th holes to cap a scintillating round.

It isthe first time in his career that he has made 11 birdies in a single round of a DP World Tour event.

The 37-year-old is chasing a fifth Race to Dubai title in a row and a record-equalling eighth in total, that would draw him level with Scotland’s Colin Montgomerie.

McIlroy went into the Abu Dhabi tournament in third position in the standings, behind leader Eugenio Chacarra and second-placed Patrick Reed.

American Reed was the long-time Race to Dubai leader after his Rolex Series victory in Dubai and win in Qatar but was recently overtaken as Spaniard Chacarra claimed a third triumph of the season at the DP World India Championship.

Chacarra shot a second-round 71 on Friday to sit well down the field on three under, while Reed registered the same score to lie further back on one over.

The top 70 available players from the Race to Dubai rankings are competing in Abu Dhabi, with the top 50 progressing to next week’s season-ending DP World Tour Championship in Dubai.
