Tattersall held his index finger around the seam of the ball and this allowed him to bowl a carefully disguised away-swinger to supplement his sharp off-break.
Tattersall, a late developer, began his first-class cricket career in 1948, at a time when English bowling was weak because World War II had decimated their pre-war pace attack.
He did not establish himself until 1950 after Roberts, Price and Nutter had left the staff and he changed to bowling mainly off-breaks, something he developed in Minor County cricket.
[3] Although he was not risked in the Tests against a powerful West Indian batting line-up, Tattersall was chosen as a reinforcement for the 1950–51 Ashes series that winter.
Tattersall went to India that winter, and on a "biting" pitch at Kanpur, he took eight wickets for 125 runs and helped England gain their only victory of the series.
[2] Returning home he found that Jim Laker, Johnny Wardle and Roly Jenkins were ahead of him in the selectors' eyes, despite taking over 100 wickets every year until 1957.
