defending his Singapore Open crown against See Gim Hock in another three-set battle, winning his third consecutive men's singles title with a score of 15–7, 9–15, 15–12. In addition to winning the men's singles title, Vass also won the mixed doubles title with his partner J. de Souza, and led his club, the Diehard Badminton Party, to victory in the first-ever inter-club championship, defeating Roseray Badminton Party 3–2. In the inter-state tournament of 1932, Vass was selected to play for Singapore against Selangor, but unfortunately, Singapore lost the contest 3–7. Nonetheless, Vass won his singles match against A. S. Samuel once again, defeating him in two straight sets with a score of 15–8, 15–9. In the Singapore Open championships held later that year, Vass won the singles title by overcoming a familiar foe in Sim Gim Hock, with the score of 6–15, 17–16, 15–12. This marked his fourth consecutive victory, which is a tournament record he still jointly holds today with the likes of Wong Peng Soon and Ong Poh Lim. In the 1933 inter-state tournament between Selangor and Singapore, Vass experienced an unexpected loss to A. S. Samuel in the singles event with the score of 7–15, 15–10 11–15, marking his first defeat in three meetings against him. Singapore ultimately lost the tie with a score of 4–6. This was also the first defeat for Vass in any competitive singles matches. During the latter half of the year, Vass could not participate in the singles event of the Singapore Open because of medical advice. However, he was able to recover in time to participate in the men's doubles, mixed doubles and inter-club events. He went on to win the mixed doubles title for the second time with his partner J. de Souza, and also played a pivotal role in leading the Diehard team to its second inter-club title with a 3–2 victory over Roseray Badminton Party. In 1934, Vass was a member of the Singapore team that defeated Selangor 8–5 in the inter-state tournament. However, he suffered his second straight defeat to A. S. Samuel in the singles tie, losing in two sets, 5–15, 11–15. In the Singapore Open, Vass returned to play in the singles event and won his fifth title, defeating Seah Eng Hee 15–9, 17–14 in the final. He followed up his success with yet another mixed doubles title, his third with partner J. de Souza.
