How easy is it to get Jacques out, and other stats...

When Rahul Dravid set the record for the most deliveries faced in Test cricket this summer, it brought to mind a quote from Bob Woolmer's majesterial The Art And Science Of Cricket.

'To review the split-second data of what happens when a batter executes a shot,' he wrote, 'is to wonder how any batsman survives more than one delivery'. Woolmer was considering the complex physiological process that the body goes through when facing an individual ball, but it did pose a simple question: what is the percentage chance of any one delivery dismissing a great player?

It's a blunt stat, as blunt as a batting average, but it is revealing too. By adding together the number of deliveries faced in Tests and ODIs, and then subtracting the number of completed innings, it's possible to produce a percentage figure.

Jacques Kallis balls faced: 41,664 dis'd: 455 % chance per ball: 1.09

Rahul Dravid
b/f: 45,374 dis: 519 % chance: 1.14

Sachin Tendulkar b/f: 48559 dis: 667 % chance: 1.37

Ricky Ponting b/f: 37,966 dis: 553 % chance: 1.46

Brian Lara b/f: 32,839 dis: 483 % chance: 1.47


The number of not outs offer another expression of the value a batter might put on his wicket:

Jacques Kallis inns: 546 not outs: 91 % chance of a not out: 16.6

Rahul Dravid: inns: 591 not outs: 72 % chance: 12.18

Ricky Ponting: inns: 620 not outs: 67 % chance: 10.80

Sachin Tendulkar: inns: 740 not outs: 73 % chance: 9.86

Brian Lara inns: 521 not outs 38 % chance: 7.29

Jacques still king of the red-inkers, then...

Where KP's at

Even if they rarely write the same thing, both Vic Marks and J-Rod had it right about Kevin Pietersen's batting against Bangladesh. It was a mad combo of boredom versus the utter determination not to be subjugated by what he saw as lesser bowlers.

I have a small wager on KP to end the year as top Test runscorer, based on his being fully fit again, the improvements he's made to his technique and the amount of cricket England have. Also factored in is his undisguised desire for greatness. I think it's still a good bet, although his lack of a hundred since last March has some people questioning him.

As his career has that halfway feel to it, and as comparisons with other England players are pointless, I ran a little progress check: KP versus King Viv, Sachin, Lara, Ponting and Viru Sehwag at similar stages of their career:

M I runs ave 100 50

IVA Richards 73 110 5579 53.64 18 23
BC Lara 64 110 5431 51.23 13 27
RT Ponting 70 109 4983 50.96 17 18
SR Tendulkar 70 109 5380 55.46 20 21
V Sehwag 64 110 5508 51.44 15 15
KP Pietersen 61 110 5102 49.05 16 18

While he has the lowest average, Pietersen still stacks up well in exalted company. Richards was in his fulsome pomp at the time, with his average and weight of scoring just peaking. Most of the others were about to enter the most productive phases as batsmen, an altitude that Sachin has almost maintained, but that Ponting has spent the last couple of years of his career slipping from.

For Viru and KP though, the next three or four years glow enticingly ahead.

Stats of the day with Haydos and the MCC

'Thousands': The number of balls Matthew Hayden had to hit with the Mongoose before he felt 'mentally prepared' to play with it.

One: The number of days it took for bowlers to start complaining about the pink ball.

Notes on stat one: Even Haydos admitted he found the short blade 'intimidating'. How glad Mongoose must be he gave this interview.

Notes on stat two: If we're going to continue to play matches on pitches like roads in forty degree heat, it won't matter if they bowl a Rubik's Cube, it ain't gonna swing or seam. It's not the ball we should be talking about...

From TMS this morning. That's why they can all bowl spin...

The harsh and strange lessons of Moneyball

Billy Beane, the hero of Michael Lewis's revelatory book Moneyball, should have been a superstar. He was a natural, a baseball player so gifted that scouts came from across America to his high school field just to watch him train. He looked a billion dollars. He was a first round draft pick for the New York Mets in 1980. 

And then he played 148 games in six seasons for four different teams. He hit a career total of three home runs. 

Billy would have been just another schoolboy phenomenon who couldn't cut it in the major leagues had he not absorbed the lesson of his own life. Instead, he realised that how baseball looked wasn't necessarily how baseball really was. 

He became general manager of the Oakland As in 1997 and proceeded to pull off the greatest ongoing giant-killing in sport by recognising that conventional wisdom meant very little in an organic, living game. 

Baseball runs on stats. Ultimately, teams, players, eras are defined by them. And Billy worked out that the stats used in baseball were wrong. Or at least, they were out of date. Standard measures like RBIs and stolen bases were relics of a bygone age. Their usage led enormously rich teams to waste huge amounts of money and time on players that would never deliver. 

Beane found his new measures of success or failure in a fanboy's book of geeky stats called Baseball Abstract. He began working with a new set of standards named sabermetrics. With them, he discovered that many effective players were being rejected by other teams because they looked weird and ugly, and because they weren't successful by the old measures. The Oakland As ended up with a bunch of cheap rejects who consistently outperformed the market. Beane now co-owns the team. He is a superstar at last. Everyone in baseball uses sabermetrics.

Baseball was reshaped by many things: the size, strength and athleticism of its players (and, it should be noted, rampant steroid use), and external factors like the demands of TV. It took 37 years for Roger Maris's single-season home run record of 61 to be broken, but once Mark McGwire had done it, it was broken twice more in three years. As soon as players understood what was possible, they went and did it.

Cricket's reshaping is happening much more quickly. Imran Nazir just got 111 from 44 balls in the ICL final, and it doesn't even seem that extraordinary any more. 

The lesson of Moneyball is, what are the stats that define this new game? Strike rate during powerplays? Economy rate whilst bowling second? Boundaries to balls faced ratio? The Batsman doesn't know, but I don't think it's the establishment that are going to find them. So it's over to the geeks and the freaks. The answers are out there.

England's limited over sides seem a little like the baseball teams that Billy Beane overcame. It's not that they're not thinking, it's just that they're not thinking the right things. Beane thought differently and came up with a team full of unfashionable freaks.

Napier, Mascarenhas, Rashid, Panesar, Wright, Key... who knows? But Moores doesn't have much longer to find out. Beane used his stats to develop and drive a philosophy on playing the game. What's Peter's?

NB: KP's post-matchers just get better. Today's was along the lines of: 'okay, we were thrashed, but we were less thrashed than last time...' Accentuate the positives, chap.
