Six feet four and pigeon-chested, Walker, who went on to complement Dennis Lillee and Jeff Thomson at their fiercest, had a front-on delivery style, bowling mainly stinging in-swing, varied by an occasional straight ball, to the right-hand batsman. He would also get the ball to cut sharply away from the batsman in the manner of a Courtney Walsh or a Waqar Younis.
Walker, interestingly nicknamed “Tanglefoot” (later “Tangles”) because of his unusual wrong-footed action, which masked what was actually a rhythmic, well-balanced delivery, was also impressively quick and could become a yard quicker on a greentop, though he could never match Lillee or Thomson, both in sheer pace and ‘aggro’.
