A bowler who achieves swing when bowling yorkers can be even more dangerous, as the ball will deviate sideways as it travels towards the batsman, making it even harder to hit.
[8] Despite the effectiveness of yorkers, they are notoriously difficult to bowl correctly and usually will be attempted only a handful of times during a sequence of several overs.
As such, a yorker is frequently bowled quickly to give the batsman less time to react and position his bat.
It is also particularly effective in the later stages of an innings in one-day cricket, because it is the most difficult of all deliveries to score off even if defended successfully.
The most notable bowlers in delivering yorkers are Pakistanis Waqar Younis, Wasim Akram, and Shoaib Akhtar, Sri Lankan Lasith Malinga, Australians Brett Lee, Mitchell Starc, Pat Cummins and Mitchell Johnson, New Zealanders Trent Boult, Shane Bond and Tim Southee, South Africans Dale Steyn and Allan Donald, West Indians Patrick Patterson, Malcolm Marshall, Courtney Walsh, Curtly Ambrose and Jerome Taylor, Indians Zaheer Khan, Bhuvneshwar Kumar, Jasprit Bumrah, T. Natarajan and Englishmen Andrew Flintoff, Chris Jordan and Mark Wood.
A yorker is usually delivered very late[dubious – discuss] in the bowling action with the hand pointing almost vertically.
Because yorkers are quite difficult to bowl they require substantial practice in order to achieve consistent success.
