'To play one innings of such magnitude is enough to put you high in the list of all-time greats but to produce two is one of the most remarkable achievements in sport.': Nearly ten years ago in Antigua, Brian Lara scored the highest ever innings in Test cricket, breaking a mark set 36 years previously. Yesterday, on the same ground, he reclaimed that record from Australia's Matthew Hayden, becoming the first batsman to score 400 in a Test, in a knock that lasted 732 minutes against a previously dominant England bowling attack. Since cricket doesn't get much of a mention here, I thought it was worthy of a post. But I'm also interested how people think single-game achievements such as Lara's compare to lifetime and single-season records such as those of Barry Bonds: is sporting greatness defined better by single performances or by the entirety of one's career?
