Cumbria's Alan Wills narrowly missed out on a place in the last 32 after Australia's Taylor Worth secured a dramatic victory in the men's individual archery event.
In the first match of the afternoon session, the draw threw up something of an 'Ashes' contest at the home of cricket, with Worth sealing a 6-5 win on a one-arrow shootout.
The match swung one way then the other as both players won two sets and drew the fourth. Worth then showed great composure to send his decisive arrow into the inner ring, while Wills hit a tight nine in response.
Wills, who was ranked 42nd following the ranking round, shot a high seven with his second arrow and saw Worth collect 28 from a possible 30 to take the first set. Wills responded well, going nine, nine, 10 with his next three attempts to draw level at 2-2.
Wills' aim drifted high as he recorded three successive eights on his way to 4-2 behind and, after he over-corrected with a low seven, Worth was left needing nine to take the match. Instead, he struck eight, halving the set for a 5-3 lead.
Wills took advantage of his chance to draw level, shooting 27 to his opponent's 25 to tee up the shootout. Worth drew first and landed dead centre, rendering an otherwise fine shot from Wills redundant.
Simon Terry, placed 50th after a poor ranking shoot, was next up for Team GB and promptly took down 15th seed Yu Ishizu 7-1.
Ishizu started ominously with two 10s to put the pressure on but closed with a wayward five. Terry, a bronze medal winner in Barcelona 20 years ago, shot a steady 26 in response to clinch a 2-0 lead.
The next set was tied at 26 apiece, Ishizu again letting himself down at the last with a high seven.
Terry then delighted the crowd by finding centre gold three times in a row in a perfect third set before closing out a 7-1 win by locating the nine ring.
