From your photo, it seems that the balls have spikes, not burrs. However, the leaves do look more clover-like than goats head leaves, which make it appear to be burr clover.
The determining test is: When the balls get larger, are they actual spikes that are capable of piercing your tennis shoe and are resistant to being removed?, .. or do they simply have a fuzzy, Velcro-like exterior that just grabs onto your socks?
If they can stick into your shoe or can puncture a bicycle tire, then it is definitely tribulus terrestris, also known as “goats head” and “puncture vine”.
If you want to know about this very serious weed, just look it up by the names I’ve given you above.
I started using glyphosate to control weeds in my yard about 10 years ago. I finally wised up and now just pull the worst weeds by hand, as much as I hate pulling weeds.
