Too early for Dallis Grass. Could be Avena fatua.

I just use a common name of 'crabgrass'. It looks out of place in my yard (as well as yours, it seems) so I grab and pull it as soon as I can get a good grip on it. Good thing is that the roots are shallow and won't disturb the ground too much. They'll continue to show up and grow throughout the growing season but look especially out of place in lawns that are still brown/dormant in the late winter/early spring, so that's when I feel the need to take them out as much as possible.
