At Hamilton
today, Newzealand made 271 for 7
(Williamson 77, Taylor 57) in 42 overs – chasing India
made 277 for 9 (Kohli 78, Dhoni 56, Southee 4-72) in 41.3 overs ~ and
the winner was !!!! …New Zealand pushed India off the No. 1 position in ODIs
with another clinical performance. Most
of the kiwi batsmen made runs - Corey
Anderson nearly blasted the fastest ODI fifty too, India had a big chase at
hand and were kept alive by Virat Kohli and MS Dhoni ….. at end of over 41 –
Indians were 275/8 … and 22 were required off 6 ….
What NZ made
271 and Indians on 275 required 22 … (the same 22 !!) … don’t be too confused….
Cricket is not only played on the field… it is played using maths tables and
calculators too… 1st ball Bhuvi got out,
2nd and 3rd produced singles…. It rained
- and match was over…. Then came
the official confirmation that NZ had won the match by 15 runs…
Those of us
following Cricket for some years know that there is nothing illogical about
this… it is D/L method that gave 2-0 lead for the hosts.
The names of Frank
Duckworth & Tony Lewis are known to
every Cricket fan. It is the rain rule
or rather how scores will be calculated when it rains in the midst of a
match. Rain rules are indeed strange;
the revised targets generally favour the chasers as they have the job cut out
in the shortened version. The Duckworth–Lewis method (often written as D/L
method) is a mathematical formulation designed to calculate the target score
for the team batting second in a limited overs match interrupted by weather or
other circumstances. The D/L method was devised by two English statisticians,
Frank Duckworth and Tony Lewis.
The basic principle is
that each team in a limited-overs match has two resources available with which
to score runs: wickets remaining, and overs to play. Where overs are lost,
setting an adjusted target is not as simple as to reduce the batting team's run
target proportionally, because a team batting second with ten wickets in hand
and 25 overs to play can be expected to play more aggressively than one with
ten wickets and a full 50 overs, and can consequently achieve a higher run
rate. The Duckworth–Lewis method is an attempt to set a statistically fair
target for the second team's innings, based on the score achieved by the first
team, taking their wickets lost and overs played into account.
The Duckworth-Lewis method
was first used in the ICC Trophy in Malaysia in 1997 and in 1998 was applied in
New Zealand, South Africa, Pakistan, India and West Indies. The method is the
invention of Frank Duckworth and Tony Lewis. Frank was a consultant
statistician and editor of the Royal Statistical Society's monthly news
magazine, RSS NEWS. Tony was a lecturer in mathematical subjects in the Faculty
of Computer Studies and Mathematics at the University of the West of England,
Bristol and chairman of the Western Branch of the Operational Research Society
On 22nd Mar
1992 - SA will ever curse the rule….
Victories over Australia, West Indies, Pakistan, India and Zimbabwe had
propelled the reemerging SA all the way to the semi-finals. Chasing 253 – rain interrupted play for 12 minutes with South
Africa 231/6 off 42.5 overs and the over limit was reduced to 43 overs with the
target reduced by 1 to 252. So suddenly when it rained, the target became 21
off a single delivery….. !!!!
Earlier in
the same tourney, rain had deprived England of the emphatic victory expected
when Pakistan were dismissed for their lowest total in limited-overs
internationals, and the smallest by a Test country in the World Cup. They were
bowled out for 74 and the target was reduced to 64 in 16 overs. It rained again and the points were split….
Pak went on to make history
