Padraig Harrington has slipped back to 10 shots off the lead at the Scottish Open after carding a third round 73.

While the Dubliner will start Sunday's final round on eight under, Jonathan Caldwell now heads the Irish challenge at Fairmont St Andrew's after a 68 moved him up to 12 under, six behind current leader Matt Wallace.

Harrington had started the third round three shots off the lead and started well with an eagle on seven and birdies on the third and sixth making up for a bogey on the second.

But further bogeys on the ninth and 11th were compounded by a double bogey on the 17th which saw the Europe Ryder Cup captain shoot a one-over round and slip back from contention.

LEADERBOARD

Caldwell, meanwhile, carded a bogey-free round to move into a tie for fifth alongside Chris Paisley and Eddie Pepperell, with a pair of birdies each on the back and front nines.

England's Wallace leads the way by three shots on 18 under after a 66. Garrick Porteus is second on the leaderboard after carding the same score, with Spain's Adrian Otaegui third, one stroke further back on 14 under.
