The emerging trends of the 12th World Cup

ICC
The World Cup is always a crucible of change for the one-day game. It's where trends are set, formulas shattered and innovations introduced in a breakneck bid to claim cricket's biggest prize. The 2019 edition might be only 15 games old but set a fascinating pattern from the very first ball when South Africa opened with the leg-spin of Imran Tahir. Countries have nine group games to put their stamp on the competition but that isn't putting a break on the risky, yet calculated, decision-making we've seen from all ten skippers. Here's a look at the numbers after 15 games. THIS IS THE WORLD CUP OF SHORT PITCHED BOWLING The earliest hallmark of the tournament is the exponential increase in the use of the short ball. 44.8% of deliveries bowled by seamers have been short, compared to 37, 37.3 and 31.9 in the last three World Cups.
Remarkably over half, 52.5% to be exact, of West Indies' balls have been short, with hosts England dropping short 48.7% and Pakistan 47.7% of the time.
It's not just those sides leading the way, with 18 out of the 35 deliveries Australia bowled to India's Shikhar Dhawan in the first powerplay short-of-length.
BOWLING SHORT BUYS
WICKETS, BUT AT A PRICE In brief, use of short-pitched bowling is proving effective in breaking partnerships but fielding sides can leak runs in the process.
A decisive shift in tactics seem to be paying off for Jason Holder's seam battery, with their collective strike rate in the first 20 overs crashing from 48 in 2018 to just over 31.
Teams have taken a wicket with every 21 short balls they bowl while it takes 33 length balls and 35 back of a length balls to get a wicket.
But short balls are far more expensive on average, with bouncers
going for 8.58 runs an over, length balls costing just 5.03 and back of a length balls 5.08.
EARLY ON, SPIN CAN STEM THE FLOW OF RUNS
South African skipper Faf du Plessis became the first captain to chuck the ball to a spinner for the opening over of a Cricket World Cup in defeat to England.
And it didn't stop there. No fewer than three Afghanistan spinners turned their arm over in the first ten overs against Australia while Mehidi Hasan Miraz has opened in two of his country's three games so far.
Mujeebur Rahman (29) and Shakib Al Hasan (28) have taken
more wickets than any other bowler in the first powerplay since 1999, so seeing them first up is no surprise.
It was the deployment of Tahir, who had never previously bowled the first ball of an ODI, that shocked England, who are the weakest of the ten countries in facing early spin, averaging a shade over 14.
However, they have only taken four early wickets. Twirlers have a worse strike rate in the first ten overs (48) than in any other stage, striking every 44 balls in the middle and 45 at the death.
It is an economical option, however, putting a brake on runscoring. Spin costs 5.50 an over in
the first ten, compared to 5.51 in the middle overs where they are used nearly nine times as much. SAVE TOP-ORDER WICKETS In their defeat to New Zealand, Sri Lanka captain Dimuth Karunaratne became the second batsman to carry his bat through a completed World Cup innings.
The opener was left stranded on 52 not out in a total of 136, the first person after Ridley Jacobs was left unbeaten on 49 in West Indies' 110 against Australia in 1999.
Karunaratne's approach early on wasn't matched by the rest of his team, but it seems the best tactical approach in the powerplay overs.
India are the pioneers of caution in the powerplay, failing to be seduced by early fielding restrictions. They didn't lose a wicket in any batting powerplay in the 2015 tournament and four years on, are adopting similar caution.
Virat Kohli's side score at a glacial 3.75 runs per over in the first ten overs, the slowest of any team, but they also lose fewer wickets. Sri Lanka score at 6.50 runs per over, by contrast, but shedding wickets has hampered their efforts and shows the way - don't go too hard too early. DON'T LOOK BACK IN ANGER There's no substitute for experience when it comes to the World Cup, and some sides are reigniting old flames in their search for success.
Aside from Anderson Cummins, whose appearances at the 1992 and 2007 World Cups bestride a recordbreaking 14 years and 361 days, the next two longest spans have been set.
It's just over 12 years since Shoaib Malik and Liam Plunkett last appeared at World Cups, both playing in 2007 and missing the next two tournaments.
Malik is a redoubtable figure, repeatedly written off as too old, but plays a vogueish role as a floating hitter who bowls canny off-spin, while Plunkett has reinvented himself as a middle-overs partnership breaker with the older ball.
