SO CLOSE: Rory McIlroy shot 65 and missed the cut by one shot after opening with a 79. MISSING THE ACTION: Tiger Woods (70) missed the cut in a major for the second time after his Masters victory. Also missing the cut were former Open champions Phil Mickelson, Padraig Harrington and Darren Clarke, who lives in Portrush.
SAYING GOODBYE: Tom Lehman missed the cut and is no longer eligible as a past Open champion because he is 60. He can return if he wins the Senior British Open. ROUND OF THE DAY: McIlroy and Xander Schauffele each shot 65.
RORY BOOKEND: Rory McIlroy began the decade at the British Open with rounds of 63-80 at St. Andrews. He ends it with a 79-65 at Royal Portrush. KEY STATISTIC: Brooks Koepka had a 69, his 14th sub-70 score in his last 18 rounds at the majors.
NOTEABLE: It was the first time in 77 major championships that Mickelson and Woods have played together as professionals that both missed the cut. QUOTABLE: "Anytime you're trying to make a cut on a Friday afternoon, especially at a major championship, you're always a little tight, a little nervous. But this one obviously means a lot, to play the weekend here." — Graeme McDowell, who grew up playing Royal Portrush and made the cut on the number at 1 over.
