For sporting events getting as much light as possible is pretty important because you’re probably going to be shooting at a very fast shutter speed.
That being said I use a 200-500mm f/5.6 and can still avoid going too high with the iso (though mostly outside during the day) and I usually shoot at f/8 so I think f/4 is still going to be okay.
