Former world number one Martin Kaymer moved into a share of the lead while England’s Justin Rose produced a stellar round of 63 on day two of the Memorial Tournament in Ohio.
German Kaymar, starting round two on the back nine, followed his opening 67 with a 68, a closing bogey on the par-four ninth the only blemish on his day.
He sits at the top of the leaderboard alongside American Troy Merritt and Kyoung-Hoon Lee, of South Korea, on nine under after 36 holes.
Rory McIlroy’s week is over however, despite an improved second round showing in Dublin. McIlroy followed an opening 75 - in which his driving was awry - with a one under par round of 71.
But it wasn’t quite enough to see him continue into the weekend, and he missed the one over par cut mark by a solitary stroke,
It was Justin Rose who laid claim to the day’s standout round, with the Englishman recovering from a three-over-par first round to move to six under overall.
The 38-year-old mixed two eagles and six birdies with just one bogey en route to a round just two off the course record and sits alongside compatriot Danny Willet three shots back of the leaders.
It was a disappointing day for Scot Russell Knox, however, who started the day three off the lead to drop into a tie for 25th on three under, while five-time winner Tiger Woods finished a shot further back after a round of 72.
