Martin Kaymer shared the clubhouse lead at the Castello Masters with Robert Allenby on Friday after play was suspended for the second day due to badlight.

A group of 50 players will complete their second rounds on Saturday.

Kaymer was one of those who had to get up early to complete his first round and his opening 63 gave him a share of the lead with Sergio Garcia.

His second round 67 put him on a 12-under par total of 130.

Australia's Allenby added a 66 to his first round of 64 to share the second round lead.

Kaymer's sharp shooting has given the French and Scottish Open Champion the chance to regain the number one spot in The Race to Dubai at his first event back from breaking his toes in a go-kart crash.

Considering he has been out since mid-August and was unable to start practising fully until the last few days, the 24-year-old was more than satisfied with his day's work.

- I was never expecting to be under 70 to be honest - he said after his eight-under par opening round.

- Maybe he's the bionic man - Allenby said of the German, who will have titanium plates and screws in his foot for another nine months.

Top of The Race to Dubai when the accident happened, Kaymer is now down to third, but the first prize on Sunday would instantly take him back above Lee Westwood and Rory McIlroy.

He did admit, however, that he was feeling it after having to play 24 holes following a three-hour stoppage for strong winds on the opening day.

- It does not affect my swing, but I was in a lot of pain the last few holes - added Kaymer. -But my expectations were not high, so it worked out pretty well.-

- I'll put some ice on it now and take it easy. The doctor told me to avoid long walks and that I won't be 100 per cent for a year.-

Garcia, playing on his home course, was among those unable to finish as the tournament tried to make up for lost time and he will resume on Saturday on 11 under with three to play.

Double Masters Tournament champion José Maria Olazábal and Indian Shiv Kapur are two behind.

Allenby, a four-time winner in Europe before moving to America over a decade ago, rejoined this season for the inaugural Race to Dubai and is already 33rd from just ten starts.

He birdied his last two holes to move alongside Kaymer.

Also going well is Italian Emanuele Canonica and England’s Sam Hutsby at nine under, while England's John E Morgan is in contention in his first event since he broke a toe stubbing it on the end of his bed just over a month ago.

Ryder Cup captain Colin Montgomerie is five under with four holes remaining and Darren Clarke one further back, but Chris Wood, third in The Open in July, withdrew after an opening 70 with a twisted ankle suffered falling down the clubhouse steps.
