GolfWRX was live this week from Riviera Country Club — one of Hogan’s Alleys, and more intimately known as “Riv” — in Pacific Palisades, Calif., for the Northern Trust Open. Just down the road from Hollywood, the course attracts many celebrity memberships, such as Adam Sandler, Larry David and Mark Wahlberg (featured below).

The Northern Trust Open also attracts the game’s top players. World No. 1 Jordan Spieth, Rory McIlroy (No. 3), Bubba Watson (No. 6) and Justin Rose (No. 7) are in this year’s field.

Check out all of the galleries from this week here.

• Wednesday’s photos

And see what those photos revealed below.

A 29-gram shaft

Fujikura’s new Zero Speeder shaft reportedly weighs 29 grams. That means it weighs closer to “zero” than most any other driver shaft on the market.

You know you’re on the Californian-swing when…

This In-N-Out truck must be absolute torture for the Tour players who travel with a dietician and are only allowed to eat unsalted peanuts and Turkey jerky during their round. But really, a quick double-double at the turn never killed anyone, right?

Changing it up

If you look closely, you can see TaylorMade’s new PSi Tour irons in Dustin Johnson’s bag, after previously playing with the company’s Tour Preferred MB irons for more than two years. He also switched to an M2 driver and fairway wood.

See Dustin’s full WITB here. 

Lefties get dunked on

If you know any lefty golfers, or read the GolfWRX forums, you know lefties are constantly complaining that equipment companies don’t offer left-handed options in golf clubs they want. This photo may just push them over the edge. The Northern Trust Open was able to get a left-handed persimmon club for a gaff, but you can’t get the new driver you want? My sincerest apologies lefties; you shouldn’t have to see this.

Back when Mark Wahlberg was Marky Mark…

…he probably played this driver; a Callaway FT-i (the “square one”). Based on a keen observation, he also has a set of Titleist 716 T-MB irons in the bag at the Northern Trust.

Now… a few wedges of note before the No. 1 revealing photo of the week.

Rory’s new rust

We shot Rory’s 2016 WITB this week, showing his new 60-degree Nike wedge. It appears to have a grind similar to one of Nike’s Engage wedges, except it’s super raw, rusted and appears to be chiseled from a block of steel. So clean.

Golf like a rockstar

This is J.J. Spaun’s Jimmy Page (of Led Zeppelin)-inspired wedge. And he has an awesome Buckethead head cover, too.

If you don’t get the reference.

That milling, tho?

PXG’s new 0311T Milled wedges are undeniably gorgeous — simply great looking wedges. And this photo provides a clear look at the circular milling marks in the sole.

The smelliest wedge on Tour

Spieth knows what I’m talkin’ about.

The ultimate Tiger throwback

This Tiger-tribute has it all from the headcovers to the silver Buick staff bag. I don’t know whose bag this is, but I know whose it isn’t — this guy from the 2007 commercial. Run the tape!

Looking back on it (no pun intended), maybe Tiger shouldn’t have been all out truck-sticking people for fun. But it was hilarious at the time.
