Yeovil boosted their promotion bid and pushed Bournemouth deeper into trouble. Wayne Gray opened the scoring with a sharp turn away from defender Neil Young before beating goalkeeper Neil Moss with a low left-footed shot.
The Cherries were mainly on top and Yeovil keeper Steve Mildenhall made fine saves to deny James Hayter, Brett Pitman and Marc Wilson.
Ex-Bournemouth loanee Leon Best scored Yeovil's second with a fine volley from a Nathan Jones cross.
