Some sort of spider wasp

I was coming back to the house from the garden. I walked around the corner and noticed a wasp fly up and away from a spider. I got to the door and it returned to the spider. I grabbed the camera and tried to get a couple shots. I couldn’t get very close without it flying off. So I snapped a picture from as close as I could get. The spider is pretty large, just slightly smaller than a quarter.
It was about 4 p.m. on August 20 near Bel Air, Maryland. Temperature was about 88F and it was rather humid since we’ve been having thunder storms pretty much ever evening.
I have a larger photo if it will help.

Dear Greg,
We are very happy to be posting your thrilling photo to our Food Chain page.  You are correct that this is a Spider Wasp.  We have identified it as
Tachypompilus ferrugineus based on photos posted to BugGuide.  Though the curled position of the spider does not permit us to be certain of its identity, we thought it must be either a Wolf Spider or a Funnel Web Spider, but the genus page for Tachypompilus on BugGuide indicates:  “Females provision nests mainly with Lycosids.”  That would indicate that the spider in your photo is a Wolf Spider.

    I have also had this little drama play out in my backyard. I have several photos, as well as some video of it. If you’d like, I can send to y’all. Or anyone else who’d be interested.
