The 2011 Open - Day two highlights

Highlights from day two of the Open at Royal St George's where Northern Ireland's Darren Clarke and American Lucas Glover head into the weekend with a one-shot lead at four under.

They lead from joint overnight leader Thomas Bjorn (72), Chad Campbell, Martin Kaymer and Miguel Angel Jimenez.

Amateur Tom Lewis, the joint first-round leader, is still the leading Englishman but he endured a tougher time as he added a 74 to his opening 65 for a halfway total of one under.
