Glenn Michibata

Insights

Best Grand Slam run came at Wimbledon in 1984 and 1991

Michibata’s top result was reaching the round of 64, which he did seven times. Those R64 finishes came at Wimbledon in 1984, 1988, 1991, at the Australian Open in 1988 and 1989, at the French Open in 1989, and at the US Open in 1989.

His only wins were concentrated early and in 1989

He played 24 Grand Slam matches and won seven, a 29% win rate. The results show his only R64 finishes were spread across 1983-1984 and 1988-1991, with no deeper run than the round of 64 in any event.

1989 was his busiest and strongest Slam season

In 1989 he entered all four majors and produced his best yearly spread: R64 at the US Open and French Open, plus R128 at Wimbledon and the Australian Open. That is the only season in the data with four Slam appearances.

His Slam career was intermittent, with long gaps between active stretches

The career spans 1983-1984, 1986-1989, and 1991, leaving a missing 1985 and no results in 1990. That pattern shows three separate blocks rather than a continuous Grand Slam presence.

He was still reaching his best Slam round at age 29

Michibata’s final recorded Slam results came in 1991 at age 29, including an R64 at Wimbledon and an R128 at the US Open. Earlier R64 finishes also came at ages 21, 22, 25, 26, and 27, showing a long but shallow peak.
