Filling in the blank spots

I found a roadside vendor with sod for sale when I was on my way home from San Antonio yesterday.  I really should have waited until mid-September when it was maybe a little cooler, but our neighbor was putting some in last week, so why shouldn't I?  He mentioned that the guy with the sod was going to be there again this Thursday, and I just happened to be going into town and spotted him on the way home. There was a bare spot under my olive tree and there was only dirt in front of the garden shed.  These two areas get lots of shade as the afternoons progress, but I think they should get enough sun in the morning.  

I got all of them in place this morning early before it got too hot out there.  I think I got them watered in pretty good.  I don't know a whole lot about grass, but this one should spread as it gets itself established and all those spaces around them will fill in..  This is next to where I park my car and in the rare moments that it does rain, no grass means we could have mud.  Of course I back my car in, so I get out on the other side, but in the event I have a passenger it would be nice to have grass instead of dirt.  

Watering seems to be the key factor for success when you put new sod down.  I think I should be able to keep up with that.
