Is the tamron 18 200mm f 3 5 6 3 di iii vc good for sports?

Not really, not for serious sport. The 18-200mm is an older APS-C travel zoom, and on APS-C it frames like 27-300mm on full frame. That reach runs out quickly for sideline action, and at 200mm the lens is only f/6.3, which is slow when you need fast shutter speeds to freeze players. The wildlife and sport guide suggests 70-200mm to 100-400mm on full frame for sport, so this lens falls short of that.

It's fine for casual shooting, like kids' games in bright light from close by. If you want more reach on the same kind of body, the Tamron 18-300mm f/3.5-6.3 Di III-A VC VXD goes out to 450mm equivalent. For a proper sports setup, start with the lenses page and add a telephoto zoom.
