Gary Lineker presents live coverage from the third round of the 137th Open Championship at Royal Birkdale, Lancashire. Often known as 'moving day', the third round is traditionally when the tournament begins to take shape and the race for the Claret Jug really begins. Roughly half of the original 154 players will tee off after the first two days and with Tiger Woods missing through injury, Europe's Sergio Garcia, Padraig Harrington and Lee Westwood will be hoping to make an impression on the leaderboard.
