BBC News: Tiger Roll: Two-time Grand National winner fails to shine on seasonal return
Racing over the Flat under 16-year-old jockey Sam Ewing, Gordon Elliott's 10-year-old was one of nine runners in the Flower Hill Maiden.
The pair missed the break from the stalls and were always towards the rear of the field before rallying late on.
It was Tiger Roll's first run since being beaten in the Cross Country Chase at March's Cheltenham Festival.
Elliott had been aiming his charge at a third Grand National in a row before the Aintree meeting was called off because of coronavirus.
However, he remains about a 12-1 favourite for the 2021 race at the Liverpool track.
