Since missing the cut at the US Open in June, the Englishman has recorded two top-tens in his last three events and he’s now ready to strike while the iron is hot.
Writing on his Twitter feed, Donald said: “Been testing Mizuno’s newest irons, the MP64s, and I like them so much am putting them in the bag this week.”
Although orders for the Diamond Muscle MP-64 irons aren’t being shipped until September 3, the new heads have landed at Mizuno’s European custom fitting line in Scotland.
The new stock also includes MP-H4 long iron replacements and MP-T4 wedges, as well as the MP A-Series of putters that are available next month.
Mizuno claims that with the shallowest cavity, the MP-64 - designed for the professional player - offers more forgiveness than a traditional blade with Mizuno’s R&D team focussed on producing soft, yet solid feel.
A quest for more feedback led the MP-64 to a thicker, bulging muscle pad behind a wider portion of the clubface.
“We flipped the design process on the MP-64,” said Mizuno’s Chris Voshall.
“Maximising feel became the absolute priority - with forgiveness added afterwards. With other more forgiving ‘player’ irons in our line like the JPX825 Pro and MP-59, we were free to really chase impact sensations.”
“Everything about the MP-64 iron is soft, from the muscle definition, the sole contours and ultimately the feel.”
