Padraig Harrington has made a bright start at the Scottish Championship and will begin the second round four shots adrift of overnight leader Adrian Otaegui. 

A bogey at the second was the three-time Major winner's only blot on the copybook at Fairmont St Andrews.

At the turn he was two-under par, but upped the ante in the chilly, autumnal conditions on the back nine. 

FULL LEADERBOARD

A birdie at the 12th was the first of four in the closing seven holes to card a round of 66, where he is joined by the English trio Chris Paisley, Aaron Rai and Garrick Porteous on six-under par. 

South African Bryce Easton and England's Matt Wallace are both a shot better off, but the man to catch is Otaegui after he carded a blemish-free 62, knocking in 10 birdies to leave the chasing pack in his wake. 

Otaegui said: "I putted really well. I also played very well from tee to green, felt confident and relaxed. Almost everything went well, 62 is really, really good." 

Elsewhere from an Irish perspective, Jonathan Caldwell hit four birdies in an opening round of 70, while an up and down round saw Gavin Moynihan card a level par 72.

Niall Kearney's three-over par round of 75 leaves him with work to do in order to make the cut, and he is one shot adrift of Cormac Sharvin.
