ARDMORE, Pennsylvania (Reuters) - Tiger Woods and Rory McIlroy played together for the first two rounds at this week's U.S. Open and they remained in lock-step after battling to matching scores in difficult scoring conditions on Friday.
World number one Woods and second-ranked McIlroy each carded a level-par 70 on a brutally challenging Merion Golf Club layout where finding rough was a virtual guarantee of a bogey with tough pin positions to tackle on the greens.
