"Our goal has been to provide Rory with the best equipment and service that would help him be the best player he could possibly be," Acushnet chief executive Wally Uihlein said. "He has been a great ambassador for the Titleist and FootJoy brands, and in turn, we are proud of how our equipment has contributed to his success. We wish Rory all the best, both personally and professionally, going forward."
"I will always appreciate the contribution Titleist has made in helping me become the player I am today," McIlroy said.
