A sampling of opinion, observations and wit collected during the second round of the U.S. Open:
Golf Channel’s Jason Sobel @JasonSobelGC: Martin Kaymer. The Germanator. Ultimate Driving Machine.
Yahoo golf writer Shane Bacon @ShaneBacon: There have been two 65s ever shot at a U.S. Open hosted at Pinehurst. Martin Kaymer has both, two days in a row.
Ron Green Jr. @RonGreenJr: The 10-shot rule is not in effect at the U.S. Open, though Martin Kaymer may be writing his own 10-shot rule.
ESPN’s Bob Harig @BobHarig: Gotta be depressing for these guys who shot -2 yest morning thinking they were in great shape ...to tee off today trailing by 8. #usopen.
Golf writer Ron Sirak @ronsirak: Martin Kaymer finishes 36 holes of @usopengolf in record -10 (130) on Pinehurst No. 2. His fight for the weekend will be with himself.
Yahoo’s Shane Bacon @ShaneBacon: I guess if you hit every fairway and hit every green and make every putt, Pinehurst isn’t that hard.
Golf writer Steve Elling @EllingYelling: Somewhere in Florida, Tiger is likely watching Kaiser Kaymer and spewing profanity at his TV, which is highest form of flattery for him.
Ron Green Jr. before Phil Mickelson fell back @RonGreenJr.: Phil Mickelson now tied for second in the US Open. Sound familiar?
Golf Channel’s Kelly Tilghman @KellyTilghmanGC: Martin Kaymer has only made one mistake this week. He thought the winning score would be +8. He’s -8. #justalittleoff
Golfweek Forecaddi @4caddie: Kaymer keeps on hitting the ball like this, the USGA may come out with an announcement of a $1 million purse for the B Flight ...
Associated Press golf writer Doug Ferguson @dougferguson405: At this rate, Phil Mickelson wouldn’t finish 2nd at this US Open. He would win the B flight.
CBS writer Will Brinson @WillBrinson: Adam Scott asked the hardest part of holding a big lead, responds “His is considerable.”
Golf Channel’s Jason Sobel @JasonSobelGC: Why it might not be over: In each of his last three starts, Martin Kaymer shot in the 60s for his first two rounds and 70s for the last two.
Yahoo’s Shane Bacon @ShaneBacon: I’m not going to say this is over, but Martin Kaymer could go triple-bogey - triple-bogey and still have a one-shot lead.
Golf writer Ron Sirak @ronsirak: Fortunately, golf does not have a mercy rule. Still a long way to go.
Caulton Tudor @CaultonTudor: In ’92, Morgan bumped into Pacific Ocean a few times and finished 77-81. Kaymer doesn’t have to worry about that possible pitfall.
ESPN Stats @ESPNStatsInfo: The last two majors have been won by the 36 hole leader – Bubba Watson at the Masters and Jason Dufner at the PGA last August.
ESPN’s Darren Rovell @darrenrovell: When Tiger is torching the field, casual golf fans call it compelling. When Kaymer is doing the same thing, they call it boring.
N&O’s Chip Alexander @ice_chip: Roy Williams sighting at US Open. #USOpen.
Caulton Tudor @CaultonTudor: 33 of the 75 Open golfers on the course right now are under par or even for their 2nd round. Who’d thunk?
Yahoo’s Shane Bacon @ShaneBacon: If this U.S. Open doesn’t get a Phil or Rory afternoon 65 you might be able to count the weekend ratings with an abacus.
N&O’s Luke DeCock @LukeDeCock: The days are beastly hot but the early mornings are absolutely gorgeous at Pinehurst.
Golf Channel’s Jason Sobel @JasonSobelGC: Hunter Mahan and Jamie Donaldson just hit each other’s balls … which is exactly as bad as it sounds.
ESPN’s Bob Harig @BobHarig: Will be interesting to hear how Hunter Mahan and Jamie Donaldson came to hit each other’s golf balls. Not good. #2StrokePenalty.
Lee Westwood @WestwoodLee: The US open is tough enough without having a go with somebody else’s ball as well!!!
Ron Green Jr. @RonGreenJr: Almost one inch of rain fell on No. 2 last night...great work by grounds crew to get the course ready...
Golf writer Ron Sirak @ronsirak: The @USGA says Pinehurst No. 2 yardage for Friday is 3,635 out; 3,793 in = 7,428 total yards.
Golf writer Ron Sirak @ronsirak: Wow! Ken Duke plays backwards from a clump of grass intentionally into a bunker then holes out to save par. A smart move rewarded.
Yahoo’s Shane Bacon @ShaneBacon: Already?! RT @RexHoggardGC: Bradley, Kaymer and Dufner put on the clock in 11th fairway (the group’s second hole).
Caulton Tudor @CaultonTudor: Bad day in Baghdad. Bad day in Bagdad. #Bubba (+7) on his way home.
Golf Channel’s Jason Sobel @JasonSobelGC: David Oh shoots 75-76 to miss the cut. “D.Oh!”
