Trailing 2-1 on aggregate, Alloa pressed for parity and James Lister had an effort saved by Craig Summersgill.
Kevin Motion, Andrew Scott and Stuart Noble also threatened for the Wasps before Lister fired against the post.
Michael Dunlop and Bryan Prunty were off target for Alloa in the second half as Annan held firm.
