Niall Kearney hit 10 birdies en route to an excellent 64 to move into contention at the Canary Islands Championship.
Remarkably, Kearney's round included three dropped shots in four holes around the turn, however, the string of birdies saw him sign for seven-under to add to Thursday's three-under 68.
Kearney made five birdies from six holes on the front nine between the second and seventh before handing two back on the final two holes before the turn.
Another bogey followed on the 11th, but Kearney bounced back in style with three in a row from the 12th before adding two more on the 16th and 18th holes.
At 10 under for the tournament, Kearney currently sits four shots off leader Adri Arnaus of Spain.
Arnaus birdied six of his last seven holes to complete back-to-back 64s at Golf Costa Adeje and enjoys a one-shot lead over South Africa's Garrick Higgo, who won the Gran Canaria Open a fortnight ago and finished birdie, eagle in his 63.
Paul Dunne was unable to make any more ground following his excellent first-round 65. The Greystones native posted a colourful round, which included five birdies, three bogeys and a double bogey to go around in level par.
Cormac Sharvin just missed the weekend cut after shooting one under to go three under for the tournament, while teenager Tom McKibbin and Jonathan Caldwell also saw their interest in the event draw to a close.
