Rory McIlroy gave back the shots he made by holing in one on the eighth as he was left trailing the record-breaking halfway leaders at the Travelers Championship.

McIlroy aced the par three in the first round, but could only find the water second time around as he double bogeyed the hole en route to a six-under-par 64.
