Ping continues to celebrate the “Ping Slam” with the second of four commemorative putters dropping next week for the PGA Championship. The “Ping Slam,” occurred when Ping won all four major championships in one year (1988), a feat that had never happened before and has not happened since for any putter brand. Each putter in the collection celebrates one of the four major championship wins.

The PLD Limited Pal 2 putter, with its distinctive Zing-style hosel and white sightline, is the second in the collection. It celebrates Jeff Sluman’s win at the 1988 PGA Championship with the club. Sluman won the 1988 PGA at Oak Tree Golf Club in Edmond, Oklahoma, where he finished with a score of 12 under par, winning by three strokes over Paul Azinger.

The putters are custom-built by Ping WRX master craftsmen at the company’s headquarters in Phoenix, Arizona. Each putter is serialized for authenticity and includes a custom headcover unique to each of the four major events.

The first of the four putters, commemorating Sandy Lyle’s 1988 Masters victory with a Pal putter was released in April.

“The buildup and attention the ‘Ping Slam’ PLD Limited Pal model received during last month’s Masters was fun to see,” said Ping Executive Chairman John A. Solheim. “We even gave one to Sandy Lyle at Augusta and he used it to sink his final putt of his last Masters. It was Sandy’s win with the original Ping Pal putter at the 1988 Masters that put us on the path to this amazing accomplishment. That brought back some very special memories for me, and we were very honored by his gesture on his last hole.

“The Ping Slam celebration is a great way to pay tribute to Karsten’s success and all he brought to putter designs while celebrating with our loyal Ping fans. When it happened 35 years ago, it was very special, and we celebrated by running one of our iconic yellow ads under the headline: Ping Putters Used To Win The Grand Slam Of Golf. What made it even more rewarding was that four different models of putters were used in the victories.”

Ping’s engineers and company historian scoured the archives to retain the integrity of the four classic designs during the milling process, spending time in the legendary Ping Gold Putter Vault to ensure the integrity of the designs.

The PLD Limited program celebrates Ping’s putter success and heritage. Last year, the PLD Limited Anser Patent 55 putter was introduced to acknowledge the 55th anniversary of the granting of the Anser patent. Each of the four versions made available throughout the year sold out in less than three minutes.

The fully milled 303 stainless steel PLD Limited Pal 2 putter will be available for purchase on pingpld.com Tuesday, May 16. Each putter is serialized for authenticity and includes a custom headcover unique to each of the four major events. Only 88 of the handcrafted putters are being offered at $990 apiece (limit one per customer).
