Playing at home on Ruckford field, Hurst scored two tries through James Hadfield and Jonathan Newland in the first half, both converted by Joe Ratcliff for a 14-0 lead at the break.
Maintaining their intensity in the second half, Hurst matched Eastbourne’s physicality and built pressure inside their opponents' twenty two.
Although the away side's defence thwarted multiple attacks, Hurst’s persistence and quick thinking led to further tries through Harry Compton, a second of the afternoon for James Hadfield and finally a sprint into the corner by Sam Johnson.
The U15As will be hoping to use all their cup experience to reach the latter rounds of this national competition; the side having won the Sussex Cup as U13s and reaching the semi-final of the same competition last year.
Update: The U15As faced a strong challenge in the form of Whitgift School at home in the Fifth Round. With the support of many from the sidelines, Hurst played some scintillating rugby but were defeated 17-10 at the full time whistle.
