Review
A record 140 entries were received at the initial stage of the 1951 English Greyhound Derby, which left the White City Racing Manager Major Percy Brown with the difficult task of selecting 48. Eight first round heats took place and Quare Customer, the Cesarewitch champion and 1950 English Greyhound Derby runner, quoted at 100-1 won his heat. Three other pre-competition 100-1 shots also sealed heat wins, they were Guineas champion Derryboy Blackbird, Junes Idol and Moon Again. Ante post favourite Black Mire and another market leader, Atomic Line both won their heats.Junes Idol won again in round two, in the fastest time so far, beating a field including Black Mire. Three Wembley greyhounds, Greenwood Tanist and Ballylanigan Tanist trained by Leslie Reynolds and Atomic Line trained by Jack Harvey dominated the remaining three heats.
In the first semi-final Atomic Line held off the challenge of the Ballylanigan Tanist, with Rushton Smutty taking the third qualifying place. The second semi-final went to 5-4 on shot Black Mire, in a fast 28.62, with Mad Miller and Rapid Choice taking the final berths for the final.
On the final night a crowd of 62,000 witnessed Atomic Line breaking from the starting traps first but Rushton Smutty forced his way inside going to the first bend. Ballylanigan Tanist's early pace put him into the lead on the outside of the pair and then he stretched that lead on the back straight. By the third bend only Black Mire looked a danger to Ballylanigan Tanist after he overtook Rushton Smutty on the back straight to move into second place. However Ballylanigan Tanist remained two and a half lengths clear at the finish line, in a time of 28.62 seconds, a new record for the final. The winning owner was Norman Dupont and it was a third Derby title for trainer Leslie Reynolds.
