In international cricket, which bowler has, or has had, the fastest run in to bowl?

The run up speed needs to be at an appropriate level to produce high linear velocity whilst still allowing the bowler to perform the bowling action adequately. Additionally, it is important to keep linear momentum as this will help the summation of forces (Bartlett, Stockill, Elliott, & Burnett, 1996). Each bowler will need a different variation of the run up as different body shapes and psychological aspects are different (Ranson, Burnett, King, 2008). ... cricketers can use reaction forces to decelerate the lower body causing the inertia of the upper body to rapidly accelerate the shoulders, hips and the bowling arm. This results in an appropriate ball release speed being applied to the bowling technique.
