Short week for Bubba: In the past 15 years, the Masters champion has missed the cut at the U.S. Open in the same year twice. Both times, the culprit was Bubba Watson.

In 2012 at Olympic Club, Watson followed an opening 78 with a 71 for a 9-over 149 that missed the cut on the number. This year was similar, as Watson opened with a 76 and came back with a 70 to miss the cut by one.

Kaymer hopes for press in Germany: Second-round leader Martin Kaymer said he understands that the German World Cup soccer team is the big story in his native country, but is hoping since the Germans don’t start play until Monday, he might get a few of the headlines.

“I’m actually glad Germany starts on Mon- day, so maybe I get some things in the newspapers about me,” he said. “Golf is not that important, but there’s not much I can do.”

Dad caddies: Kevin Kisner got a jump on Father’s Day by coaxing his own dad out of the gallery Friday to serve as a last-minute caddie.

The 30-year-old was already 8 over and certain to miss the cut in his first national championship when he arrived at Pinehurst’s 16th.

Kisner said a double bogey there convinced him to send regular caddie Duane Bock into the crowd and turn the bib over to Steve Kisner.

“At first I was a little concerned about interfering with the group,” Steve Kisner said. “One of the guys still had a chance to make the cut and I didn’t want to change the flow. But Kevin insisted, and once he insisted I was glad to.”

Hunter Mahan missed the U.S. Open cut by one shot after penalty.
