Newer lawn, grass weed control

I moved into a new house last year and had about 2 acres hydroseeded, which has come up very well. There is one grassy weed growing in the yard and I'd like some help in identifying what it is so I can target my control (see pics).

I've made 2 Tenacity applications to the yard (3 weeks apart) and it's work great on everything but this weed. Tenacity seems to bleach out whatever this is, but doesn't kill it.

Overall since my lawn is surrounded by farmers fields on 3 sides, I'm very happy with how things look, but getting this one weed under control would be icing on the cake.

It does look like quack. Seems that an herbicide called Certainty is recommended for this type of weed?

With the rhizomes spreading underground, manually pulling these seems like a losing battle.
