OK:
In England this year, Mike Hussey got out for the first time in a ODI. His batting average thus became 229.
In the Third Test in the Ashes, Michael Vaughan's match-turning 165 came in a partnership of 229 with Marcus Trescothick.
Here's another interesting one:
"In an anecdote which illustrates the difference in attitude between the two Waugh twins Ken told us that when the NSW skipper Geoff Lawson declared at 4/601 after the Waugh brothers had broken every Australian partnership record in the book with a fifth wicket partnership of 464* in their match against Western Australia in Perth during the 1990-91 season, Mark Waugh is said to have been very pleased and quite happy to rest on his laurels - after all, he was 229* at the declaration . His twin brother Stephen, on the other hand, who was 216* when the skipper pulled the plug on their act, is said to have been furious with Lawson for declaring, expressing the view that they could have made 1000 runs out there, such was their mastery over the pitch and the bowlers who were pitted against them on the day. Incidentally, those WA bowlers included Alderman, Reid, Matthews, Moody and MacLeay, all of whom had long and successful careers in their own right."
So that would be Mark Waugh scoring 229* in the biggest fifth wicket partnership in Australian history. It is also Mark Waugh's highest ever first-class score, I think.
I give up ...
