I do not know how closely you study, and how much credibility you give to, that delightful piece of technology creatively dubbed "Hawkeye", but it shows (with what may be called conclusiveness only if you believe in its fabled accuracy) that a cricket ball, when trundled, loses an enormous amount of pace after hitting the deck.
This always seemed the case with Glenn McGrath. Had a he bowled a foot or so fuller, he might not have been as great or as temperate a bowler, but he would have maintained his status as a genuine speedster for far longer than he did.
Still, whatever the facts about his speed and how much of it he lost after his deliveries introduced themselves to cricket wickets, he hardly deserves mention in a thread devoted to medium-pacers.
Forgetting Mr Akthar one feels...
Annoyingly, in the case of Shoaib, I am forced for once to agree with the odious bond21. The Rawalpindi Express has been as inconsistent speed-wise of late as he has been inconsistent temperament-wise throughout his career.
Still classifies as "Right Arm Fast" IMO, he was still bowling deliveries in the early 150s in the series v India.
Fazal Mahmood has to be one of the best if not the best ever medium pacer.
I never saw him bowl a spell at 150kph in India. A ball or an over maximum and then down to the mid 130s.
IMO, Bedser falls squarely in the medium bracket and McGrath way outside.
Anyway, with the discussion in the Wisden Cricketers thread about Barnes and what type of bowler he was, would be interesting to see if people would fit Appleyard into this 'medium' category.
Some of these, of course, were not exclusively medium-paced and, to make matters worse, not Pakistanis either. Nevertheless, they were comfortably better than your offering when they were cultivating the medium-paced stuff.
