Even for those who do not class themselves as especially big golf fans, the Ryder Cup is always worth a watch for the chance to see America and Europe's best golfers pitted against each other in thrilling match-play competition.
While a three-day event that, at this time of year, clashes with so much other sporting action on the weekend is not necessarily something you would want to sit through all the way, its final day in particular is at the very least worth dipping in and out of.
Many of us however will be glued to our screens for the duration of this final session (in which 12 singles matches are contested by all members of both teams) when the Cup either comes down to a tense and earnestly fought battle for the deciding points or an entertaining declaration of one team's superiority.
Bleacher Report's golf section will be providing analysis and reflection throughout this weekend, but before the event gets underway, why not chime in with your opinion about what you think are the greatest single days in sports.
In addition to the Ryder Cup's final day, here are a further five of those such days that deserve recognition too.
This is not a definitive list, rather they are among the favorites of this writer, so after you have taken a look feel free to suggest your own and maybe what you think to be the greatest single day in sports.
