The first tie of the inter-zone playoffs in Jakarta pitting Canada against India was another rousing 5–4 battle featuring numerous close matches. A few days shy of his eighteenth birthday, India's Prakash Padukone showed signs of future greatness by defeating both Jamie Paulson (climbing back from 6–14 down in the third) and Bruce Rollick in titanic three game struggles. Paulson, however, won his remaining singles and both of his doubles with the ebullient Yves Pare. Ex-Thais Raphi Kanchanaraphi and Channarong Ratanaseangsuang completed a sweep of the doubles allowing Canada to advance to the semifinal against Denmark. [1]

Unfortunately for spectators, the Canada vs. India tie was the last of the dramatic, issue-always-in-doubt team contests which had characterized much of the 72-73 Thomas Cup series. Canada, which needed to be at its best to be competitive against a typically talented Danish lineup, was flat instead and lost tamely 0–9. Svend Pri, playing both singles and doubles, won all of his matches in straight games. Kanchanaraphi and Ratanaseangsuang, each of whom had winning Thomas Cup records against the Danes in matches dating back to 1961 and 1964, found the going rougher in their mid thirties. Dropping only two games in the tie, Denmark advanced to the Thomas Cup final for the fourth time. [1]
In the other semifinal Thailand, an upset winner of the Asian zone qualifier, fought hard but was out-gunned by an Indonesian team that was perhaps the best yet in their then almost unbroken string of Thomas Cup success. Thailand's diminutive but highly talented Bandid Jaiyen wore down the veteran Muljadi in three games, but the Thais were unable to capture another match. Traditionally strong in doubles, the Thais dropped eight straight doubles games, only one of them close, to Indonesian pairs containing future "legends" Tjun Tjun, Christian Hadinata, and Ade Chandra. With Rudy Hartono winning all four of his matches for the fifth consecutive time, Indonesia advanced to play in its sixth straight final. [4]

Muljadi for Indonesia and Henning Borch for Denmark were the only holdovers from the controversial 1964 final between the two nations (they had faced each other at third singles with Muljadi, then known as Ang Tjin Siang, winning). [8] Both ended their Thomas Cup careers with this '73 final. It was a happy ending for Muljadi who outlasted Elo Hansen in three hard games in the first match of the tie, and then beat a jaded Svend Pri in straight games on the second night (thus completing a perfect 6–0 singles record in the championship rounds of Thomas Cup). Pri was jaded on the second night largely because of his colossal effort on the first night in handing Rudy Hartono his first Thomas Cup singles loss. Smashing accurately in the first and third games and staving off several match points Pri threw his racket to the crowd at the conclusion of the battle. Sterling achievement though it was, it did little to spark a good Danish team against a generally better opponent on the opponent's home court. Hansen became ill and defaulted his second night's match to Hartono. Budding Danish star Flemming Delfs faded after the first game to lose the third singles match to Amril Nurman 4–15 in the third. The doubles matches were less competitive. 1970 All-England champions Tom Bacher and Poul Petersen, never at their best in the tropics, lost tamely to Christian and Chandra and to Hartono and Tjun Tjun. As for Henning Borch, the only Dane at that time to have competed in five inter-zone campaigns, it was a final disappointment. He and Svend Pri failed to score more than eight points in any of their doubles games. Indonesia won the tie 8–1, and with it their fifth Thomas Cup title. [9]
