Can You Identify This Weed In My Lawn?

Question

This weed showed up in my lawn last year. It is an invasive weed that has quickly spread through the Bermudagrass in my backyard. I can’t figure out what it is or how to get rid of it. Hoping you can help me.

Answer 1

It looks like it could be sheep sorrel or red sorrel. A post emergent weed killer should take care of it, but it is considered problematic.
