Peak came at Wimbledon in 1977

Yuill’s best Grand Slam result was a single R16, and it came at Wimbledon in 1977 at age 28. That was his only run beyond the R32 stage across 21 tournaments.

1977 was his strongest season by depth

In 1977 he reached the R16 at the French Open, R32 at the US Open, and R64 at Wimbledon. No other year shows three results all inside the top three rounds of the draw.

His early career was his most productive stretch

From 1973 to 1974, Yuill posted his two best pre-1977 results: R32 at Wimbledon in 1973, then R32 at the French Open and R64 at Wimbledon in 1974. Those were his only results better than R64 before 1977.

Late-career results flattened out at the first two rounds

From 1978 through 1980, he never advanced beyond the R128 except for two R64 finishes at the French Open in 1979 and 1980. In that three-year span, 7 of his 8 appearances ended at R128.

His Grand Slam record was close to break-even but still negative

Across 39 matches, Yuill finished 18-21, a 46% win rate. He played 21 tournaments in his Grand Slam career from 1973 to 1980, so his average was fewer than two matches per event.
