Appears to be a wild lettuce. I would guess Prickly Lettuce (Lactuca serriola), but can't see if there are spines along the veins on the undersides of the leaves.

I agree with Kent. I get this all the time. It pulls easily if gotten to early.

It does resemble Prickly Lettuce (Lactuca serriola) a lawn weed that we have here in Florida.

Pulling that type of weed is much easier following a good rain storm. After a rain I pull similar-looking weeds in my neighbor's yard to get exercise and to keep his weeds from re-seeding into my yard.

I agree with Lactuca serriola.

It has the characteristic prickles on the underside midrib. And, all parts of the plant exude a milk like goo when broken.

Excellent! Thumbs up
I wish everyone would take a series of photos like that for each 'weed' and 'plant' in their garden. It would be a great addition to the database.
