Tiger Woods has much to do if he's to win the memorial Tournament at Muirfield Village for the fourth successive year.
With one hole to play of his second round he's nine behind the leader Bob Tway on one over par.
Last week he won the Deutsche Bank SAP tournament in Germany before dashing back to Columbus Ohia to defend the Jack Nicklaus-backed event he has won since 1999.
He had a first round 74 but was unable to make much impression on the leader Tway who added a 71 to his overnight 65 to reach eight under par.
Stuart Appleby of Australia got to within one of the leader but dropped back to five under alongside Stewart Cink, Skip Kendall and rookie Heath Slocum.
Currently tied second after eight holes of their second rounds are Harrison Frazar and Vijay Singh on six under par.
Best placed European is Sergio Garcia, on even par after 16 holes of his second round.
