Hi Ryan - there could be a few reasons.
1 - animal peeing on it - although it looks the least likely reason.
2 - uneven surface so the mower blades are scalping areas which are higher
3 - problem below ground - ie an area of concrete or something similar preventing proper drainage
4 - weedkiller damage or excess of a weed and feed product - though again, I'd say that's unlikely if it's exactly the same area
Are any of those a possibility?
