Two is better than one for the organisers of the Heineken Open who have confirmed that legendary doubles pairing, Mike and Bob Bryan, will line up in next month's event in Auckland.
Their list of achievements is staggering with more than 100 career titles, 16 grand slam doubles titles, seven grand slam mixed doubles titles and four season-ending championship titles between them.
The Americans have been the season-ending No 1 team in the world 10 times since 2003, including the past five years on the bounce.
The identical twins have won more games, more matches, more tournaments and held the No 1 ranking for more weeks (397) than any other player.
The duo continued their dominance on tour in 2014, winning ten titles, including six at the masters level, while they reached the final on a further three occasions. Their win at the US Open in September meant the twins have won at least one grand slam every year for the past ten years.
