Help to ID this pepper?

[MSchep]

Hi All,
This season I had an extra spot for a pepper in my EB, since one of my planned starts went south early. I picked up a plant from my local store that was labeled a Fresno Chile, but the first couple fruit set says otherwise. Just curious what others think I might have on my hands here?

The largest of the fruit in the pic is about 2" long at this point, and maybe ¾" at its thickest point. The plant itself is doing well, but shorter than it's jalapeno and serrano neighbors, and the leaves are smaller. The fruit set is noticeably more prolific than the others.

Looking forward to the community's thoughts on what this guy is.

Thanks!
