International captain Nick Price named Shigeki Maruyama, Mark McNulty and Tony Johnstone as his assistants for the Presidents Cup on Tuesday, while U.S. captain Fred Couples selected Jay Haas.
Couples will name additional assistants in the coming months.
This marks the first time that each captain has the option of naming three official assistants.
Maruyama, who has won three PGA Tour events, has an overall record of 6-2-0 in the Presidents Cup, including a 5-0-0 showing during the International team's lone outright victory in 1998.
McNulty, a Presidents Cup teammate of Price in 1994 and 1996, has a 3-4-2 overall record in the event. He currently competes on the Champions Tour.
Johnstone, who, along with Price and McNulty, hails from Zimbabwe, spent most of his career on the South African Sunshine Tour and the European Tour, where he won the 1992 British PGA Championship.
"Choosing my three captain's assistants was really very easy for me," said Price. "I grew up playing golf back home with Tony Johnstone and Mark McNulty. Maruyama-san was an inspiration to all of us in every Presidents Cup team he played on. His enthusiasm, dogged competiveness and incredible team spirit are things I will never forget."
Haas, a 9-time PGA Tour winner and 16-time victor on the Champions Tour, represented the U.S. in the Presidents Cup in 1994 and 2003, where he posted a combined 5-3-1 record. He also served as Couples' captain's assistant in both 2009 and 2011.
"Jay has really been my right-hand man these past two Presidents Cups, and I know I couldn't do my job as captain without him," said Couples. "Jay has been one of my closest friends for many years. I rely on his leadership qualities, organizational skills and ability to help bring the team together to play their best, but also have a great time in the process."
The President Cup returns to the United States at Muirfield Village Golf Club from Oct. 3-6, 2013.
