Astrophysic a star performer

Astrophysic used the rails alley to run down the fast jumping Westeros before holding out Crashing Packs to score by half a length in 22.44.

The brilliant dark brindle from Paul Stuart’s kennels has saluted in his past six starts and has 36 victories in total over the 405m journey.

On Saturday night, Party Hotshot delivered an ominous performance in the heats of the Summer Chase (647m) and will start favourite for the final this weekend.

The talented Ben Abercrombie-trained race dog came from near the tail of the field with a barnstorming run to score by more than four lengths in the fastest qualifying time of 37.02.

In the other heat, Fachoong surged late to snatch a narrow victory in 37.25.
