Björkman and Kevin Ullyett, Lukáš Dlouhý and Leander Paes, and Erlich and Ram's replacements Mariusz Fyrstenberg and Marcin Matkowski. Red Group top duo Bob and Mike Bryan, who had withdrawn from the 2007 Tennis Masters Cup due to an elbow injury for Mike Bryan, were set to face Mark Knowles, one of the two separated defending champions, and new partner Mahesh Bhupathi, for the fourth time in 2008, after meetings in the Australian Open quarterfinals (won by Bhupathi/Knowles), in the Miami Masters final (won by Bryan/Bryan), and in the Cincinnati Masters semifinals (won by Bryan/Bryan). The Bryans had also defeated Knowles, partnering fellow Bahamian Devin Mullings –then ranked 1017 in singles, not ranked in doubles– in the first round of the Beijing Olympics doubles tournament. The Bryan/Bryan-Coetzee/Moodie encounter was also a repeat of a matchup having already occurred three times in the season, at the Indian Wells Masters (won by Bryan/Bryan), the Miami Masters (won by Bryan/Bryan), and the Monte-Carlo Masters (won by Coetzee/Moodie). Coetzee and Moodie, after defeating the Bryans in Monte-Carlo Masters' quarterfinals, went on to lose in the semifinals to Bhupathi and Knowles, in their only meeting before the Masters Cup. Occasional doubles team of Cuevas and Horna, who competed in only three tournaments in the year, had a head-to-head record against only one of the three other teams, having upset the Bryan brothers in the French Open quarterfinals, en route to their Roland Garros title. In the Gold Group were set rematches of the Wimbledon final, between champions Nestor and Zimonjić and Björkman and Ullyett, whose encounter at Wimbledon (won by Nestor/Zimonjić) was the only one in their career, as well as of a Wimbledon semifinal between Nestor and Zimonjić, and Dlouhý and Paes (won by Nestor/Zimonjić). Nestor and Zimonjić, and Dlouhý and Paes had met three times in the year before the Masters Cup, in the Wimbledon semifinal first, then in a Toronto Masters semifinal (won by Nestor/Zimonjić), and a Cincinnati Masters quarterfinal (won by Nestor/Zimonjić). The second seeds' perfect record in 2008 against Dlouhý and Paes also included a victory of the pair over Paes and Tommy Robredo in the Hamburg Masters semifinal, and of Nestor and Frédéric Niemeyer over Paes and Mahesh Bhupathi in the first round of Indianapolis, where both players were preparing for the Beijing Olympics. Previous matchups between the group's teams also included a 2–2 head-to-head record between Nestor and
