Invasive weed/grass in my lawn - Page 3

I'm 99.9% sure it is not what most of us here in the Midwest call
crabgrass.  I have a few patches of crabgrass, but nothing like the
number of patches of what I showed in the picture.  I hope to get a
sample to our local Morton Arboreteum, and see if anyone there has any
ideas.  But, I'm not too hopeful as they are primarily interested in
woody plants and trees, not grasses.

It looks like crabgrass to me.  The simplest way to eliminate it is to not
let it set seed (mow and compost the clippings) or germinate (pre-emergent
herbicide applied in late spring, after cool season grasses have germinated
but before crabgrass has germinated).

Mowing is pretty effective, since the seed is produced on stalks above the
height of a typical lawn.  There won't be much to mow except those stalks,
so it may seem like not worth the effort, but mowing pays off the following
year.  Mowing alone takes a few years to control crabgrass, until the seed
bank in the soil is used up.

I'm no expert, but it looks almost like St Augustine grass, but I don't
think it would survive Chicago winters.
Find some MSMA and try it. If it's crabgrass, dallisgrass, goosegrass or
the like, it'll kill it.
They still have some here

Not crabgrass, as crabgrass is an annual.

Could be Nimblewill:

It's perennial, has the leaf blades coming off of stalks so blends horribly
with typical lawn grasses, starts growing late, turns brown early.

You can spot treat with something like Roundup (or try dig it out) and
then patch with good  seed or sod.

I've got some patches of it way in the back, and it doesn't play nice
with the other grasses at all.  Nor is it pleasant to walk on.
