Hi. I laid a new lawn last year and it looked great. This year however the front half seems to be thin and I some very course grass growing in it. What is this grass it seems to grow thick stems out from the plant horizontally squashing the other grass around it. Also where is it likely to come from and is there a way to get rid of it?I Here is some pics. 1 of a good patch of lawn another of a infested part and another showing an individual offender.

looks like a grass to me.

as for remedies, probably came in with the sod you put
down, so you're going to have to talk to the people you
bought the sod from.

if you don't want it to spread take it out before it
goes to seed.

I agree it looks like some kind of undesirable grass. Which is the bad
news, because there are few selective herbicides that are grass specific
to deal with that kind of problem.

From a practical standpoint, if it's just a few spots that are not big,
I'd probably kill it with Roundup (glyphosate) and when it dies off,
go get some new pieces of the same sod to repair it. Left alone it will
likely spread. You could try Weed-B-Gone or similar weed killer,
but I doubt that will be effective, it works on mostly broadleaf weeds.
And like SB said, whatever you do, try not to let it go to seed. But
even with mowing, usually some seedheads manage to grow sideways enough
to escape. And some grasses can also spread by stolen, so that's even
worse.
