Gainsborough Trinity took a big step to confirming their Blue Square Bet North play-off place while Worcester City's promotion hopes came to an end.
Leon Mettan gave Gainsborough the lead before a good move involving Tom Thorley saw Greg Mills level.
Gainsborough scored again before half-time through Luke Waterfall.
City equalised through a second-half Thorley penalty after Danny Edwards had been fouled in the box.
Worcester manager Carl Heeley told BBC Hereford & Worcester: "We threw the kitchen sink at it in the last fifteen minutes and unfortunately couldn't force the win."
