The Yorkshire side were 32-15 ahead on the hour mark, before Esher scored two converted tries to secure both a losing bonus and a four-try bonus.
Ionians missed out on a four-try bonus and relied heavily on the boot of scrum-half Isaac Green, who kicked three penalties and a conversion, while stand-off Lee Millar slotted over two penalties.
Right wing Sam Wilson, left wing Daniel Tai Sen Choy and No 8 Laurence Cowen scored the hosts tried to ensure the win.

Lennard opened the second half with another penalty and then converted when No 8 Martin Protheroe touched down for a try, giving Doncaster a 13-12 lead, but Cleckheaton got back in front with their final try by James Wilson, converted by Ronan Evans.
Lennard added two further penalties to equalise and Phoenix clinched the win when winger James Wright raced over and Lennard converted from wide out.

After Peters and Driffield’s Will Brigham had exchanged penalties, Pocklington had another dominant spell which brought tries by centre James Flint and replacement prop Dan Elvidge before the Woldsmen finished with tries by second row Simon Walgate and No 8 Will Burns.
