The other heats were won by Centre Account (28.59), Alannas Spark (28.30) and Knockanroe Rover (28.30).
Second semi: 1 Knockanroe Rover, 2 Im Frankie, 3 Alannas Spark, 4 Hartwood Tippi, 5 Centre Account (m), 6 Caseys Shadow
Alannas Spark is clearly a very big danger, but it is hard to see the bookies being too generous about her given her draw in one and, indeed, it is not inconceivable that the box could work against her if she fails to trap smartly.
Whatever the fate of Alannas Spark, Charlie Lister should be on the mark at Crayford courtesy of Scurry winner Lissenair Luke in the dogs' semi at 9.56pm.
Spark's breeder Paul McCarthy won a novices' race at Clonmel with Persian Spark in 29.99sec, and the Midland Oaks winner is from her first litter.
She again has her favourite draw in six and, having shown top class form to reach the Blue Riband final here last month, can lead Alannas
Spark (badly drawn in three), unlike in Manchester when she came from behind.
Spark is their 2-1 favourite for the big race, whilst the Vinnie Jones-owned Smoking Barrel is rated a 4-9 chance in the marathon.
Alanna Ketley died overnight on March 18 and as a result her personal Facebook page became a memorial.
But for no apparent reason the page suddenly went blank a few days later and Alanna's mother Nicky Ketley was locked out.
I had a message from my daughter's friend to say Alanna's page is back.
Alanna Ketley was just 18-years-old when she passed away overnight on March 18.
Now Alanna's mother Nicky is fighting to keep her memory alive for all her family and friends on her memorial Facebook page.
