Unusually big for a normal spider. Aggressive little spider, if you put your finger to the glass he would charge over towards it. You will be glad to know he was released into the wild to probably terrorise other insects and spiders!
This looks like a Giant House Spider, Tegenaria duellica. Its probably an adult male, but its a weird time for him to be around, I haven't seen one all year, but I know a couple of people who have seen one recently.
