Callaway has announced the introduction of its new Mack Daddy PM-Grind wedges, designed in conjunction with Phil Mickelson.

The five-time major champion is renowned as one of the best short-game exponents in the world.

He worked closely with Callaway’s research and development team to craft PM-Grind wedges that conform to his desired specifications.

One of the main features of Mack Daddy PM-Grind wedges is a higher toe. This moves weight higher up on the club, making delicate green-side shots easier.

The increased surface area, meanwhile, is designed to inspire confidence so golfers can be more aggressive on approach shots by accelerating properly through the ball.

“We made this high toe wedge last year. The first time I used it was at the USPGA Championship and my short game was phenomenal – it was the best it had been all year,” said Mickelson.

“I think this wedge is going to have the same impact as some of our other successful club launches because Callaway were willing to take a risk and try some new things.”

The Mack Daddy PM-Grind wedges will be available in four lofts, from 56 – 64 degrees.

Roger Cleveland, Callaway’s master craftsman, added:

“One of the toughest short-game shots is from greenside rough, where the club can easily slide under the ball without making contact.

“To give him an edge in the majors, when the toughest possible course conditions are expected, Phil wanted to create a club that would counter this.

“He came to us with the idea for Mack Daddy PM-Grind wedges and has been passionate about developing the product to his exacting standards throughout the process.

“After testing every prototype on tour, Phil’s evaluation and feedback has helped ensure the final product offers performance that is demonstrably superior and pleasingly different.”

Mack Daddy MP-Grind wedges will be available from May 1, 2015 with an RRP of £99.
