10th Hole Scatter Chart Autopsy, Northern Trust Second Round

What stands out as the 311-yard hole played to a 4.138 scoring average?

Probably how many more guys are trying the lay-up up compared to last year. And based on the scores, that's not helping them score any better. The 10th is currently the 8th toughest hole at Riviera for the 2013 Northern Trust Open.

Phil Mickelson's otherwise excellent 67 was marred by a double bogey on 10. He talked about it after the round:

Q.  Didn't see your second shot on 10.

PHIL MICKELSON:  I hit a drive way left and hit it in some of the trees there; I hit somebody; kind of fatted it into the chipping area.  And the chipping area is so tight, I couldn't get a wedge underneath it, bladed across the green in the bunker.  Hit a bunker shot to six feet and missed it.

Q.  You know you couldn't get a wedge underneath it?

PHIL MICKELSON:  It was a really precise shot.  I mean, as tight as these areas around the green that are shaved, it's tough to get a wedge underneath it, I really didn't have a chance.  I could have putted it 25 feet to the side.  Looking back, it would have saved me a shot but that's not really how I like to play.
