If you thought that lawsuit over the cult favorite Kirkland Signature golf ball sold at Costco and Acushnet, the parent of the game’s top-selling golf balls under the Titleist brand name, was withering away into oblivion, think again.
Nearly five months after Costco, the U.S.’s largest membership-only warehouse club, filed a lawsuit in U.S. District Court seeking a declaratory judgment that its ball was not infringing on any Acushnet patents, Acushnet responded with a blanket denial of any and all Costco’s claims. Then, it returned the favor with a 284-page countersuit, alleging that the Kirkland Signature ball not only infringes on 10 Acushnet-owned patents having to do with golf ball core and internal construction and dimple patterns, but that the Kirkland Signature guarantee amounts to false advertising.

Hayden Wood, son of former PGA Tour player Willie Wood, set a U.S. Amateur scoring record in taking medalist honors at Bel-Air Country Club in Los Angeles on Tuesday.
Wood, whose father is a former U.S. Junior Amateur champion, completed 36 holes at nine-under par 131, a 36-hole qualifying record, eclipsing the record of 132, set by Hank Kim at the TPC Sawgrass in 1994.

Here’s what he had to say about his change to a mallet putter, why he uses irons with zero offset and the changes he made to his driver setting and 60-degree wedge before the PGA Championship.
Last year you visited Scotty Cameron’s studio and walked away with the putter you won the PGA with. What was that experience like?
Anytime you go to the Studio and work with Scotty and Paul Vizanko, you learn something new every time. It’s an unbelievable experience. It’s really fun. You walk out of there with more knowledge than when you go in there. I feel like I leave having something good to work on with my putting and my mechanics. It’s not just looking at different putters. You’re looking at what putters are going to give you the best roll ..
