Luke Molyneux squandered a number of chances for the visitors at Holker Street.
Northern Irish youngster Kelly coolly slotted home from close range in the 83rd minute.

Dangerous Molyneux hit a low free-kick into the side netting on the stroke of half-time before Wyll Stanway kept his header out after the restart.
Sam Foley forced a good save from Chelsea loanee Teddy Sharman-Lowe to tip his effort past the post before Neo Eccleston rattled the bar with a powerful strike.
