That doesn't mean second-round co-leaders Robert Streb and Jimmy Walker aren't going to hold on to their position on Saturday and sleep on the lead going into the final round, but there is no reason for either player to feel comfortable.
That's because Jason Day and Jordan Spieth are charging. Streb and Walker both have scores of nine-under par as they prepare to tee off Saturday afternoon at Baltusrol in Springfield, New Jersey, and both have played razor-sharp golf through the first two rounds.
Streb fired a spectacular 63 in the second round, while Walker followed up on his opening round of 65 with an impressive 66 in the second.
