It's been rare in his career, but Tiger Woods has turned in the occasional big number for either 18 or nine holes.
In fact, in 2015, Woods turned in his two worst 18-hole scores ever as a professional, as part of a season where he missed the cut a record four times.
Then in 2022, Woods turned in his two worst scores in major championships, shooting 79 in the third round of the PGA Championship before withdrawing from the tournament. In the opening around of the 2022 Open Championship at St. Andrews, Woods shot 78 on the Old Course, which ultimately contributed to him missing the cut at the 150th playing of the game's oldest major championship.
Woods hasn't been completed immune from bad rounds and big numbers over the years, but he has been remarkably consistent as a champion.
