To fall into the sun you would have to negate most of Earth's orbital speed which is about 29.8 kilometers per second. To escape the solar system you need about 42.1 km/s of speed. It actually takes less energy to yeet yourself out of the solar system from Earth than to fall down into the sun. If you threw an object from Earth's orbit along Earth's orbital path an extra 12.3km/s that object would be going 42.1 km/s and eventually but barely leave our solar system. Unfortunately throwing things at kilometers per second by hand is not possible, 1 km/s is just under 2237 mph. Of course with atmospheric drag for most low orbit satellites things will come down eventually, in which case throwing something the right way could add or subtract from the time it will stay in orbit, but that would be highly dependent on where you started. And LEO is already like 7.2 km/s or about 16,000 mph. Standing on a massive enough satellite using a large stick or like a sling staff would certainly help you get more speed in your throw though. A 100 mph baseball throw really wouldn't be that significant though.
