HONOLULU – John Daly is using a set of wedges at the Sony Open this week that have square grooves, even though new U.S. Golf Association regulations require V-shaped grooves.
And his wedges are legal, too.
Daly said on Thursday he was using Ping wedges that he’s had since 1986, which he hasn’t used on tour in nearly 20 years. Dean Wilson also pulled from his garage a Ping lob wedge he said was made sometime in the 1980s.
A USGA official says those Ping wedges, which were made around 1990, can still be used because they were allowed under a settlement when Ping sued the governing body.
Square grooves typically produce higher spin rates and steeper landing angles than V-shaped grooves, although it’s unclear how much the old wedges might help because they were manufactured so long ago.
