What is this light green weed making my lawn patchy?

This light green or yellow plant thrives in poor-quality soil where tall fescue struggles to grow. Because it lacks the long runners typical of Bermuda grass, it is difficult to confidently identify. Without knowing exactly what the plant is, you cannot find the proper treatment to eliminate it and fix your patchy lawn.

“I don’t find any super long runners that typically point to Bermuda. The soil is definitely not high quality here, my TTTF (Resilience II) grew poorly here.”source ↗
