TOPSHOTS England's Ian Poulter is handed a giant golf ball to sign on the 4th tee during practice on The Old Course at St Andrews in Scotland, on July 14, 2015, ahead of The 2015 Open Golf Championship which runs July 16-19. US golfer Jordan Spieth arrives at St Andrews with a shot at becoming just the second man - after Ben Hogan in 1953 - to win the first three majors of the year, setting up the mouthwatering prospect of him pulling off the Grand Slam at the PGA Championship next month.
