DUBLIN, Ohio — The top three players in the world came into the Memorial Tournament fresh off victories. A lot of good that did them. Rory McIlroy, the world’s No. 2 golfer, backed into a tie for fourth. Top-ranked Jason Day finished tied for 27th, and Jordan Spieth was tied for 57th.
The top three, who had combined for 15 top-10 finishes in 32 starts this season, were no match for William McGirt and Jon Curran, who came into the week with a combined six top-10 showings in a combined 38 starts. McGirt closed with a one-under-par 71, and Curran a 70, to finish regulation tied for the lead at 15-under 273.
