Understood that you have the distance accurately sorted and it is not a guess.
I re-iterate that your camera’s ISO and F/5.6 could be limiting, if the clouds come over.
On a sunny day – if the sun is behind you – typically with that lens you will be at:
F/8 @ 1/1600s @ ISO400.
If you are shooting with the sun on the side let’s say you’ll need to open up ⅔Stop – so:
F/8 @ 1/1600s @ ISO640.
Still a sunny day and the sun is behind the players and you are shooting into the sun - then you’ll need to open up maybe 1½ or 2 Stops:
F/8 @ 1/1250s @ ISO1600.
OK so taking those as a guideline for the three possible main positions of the sun, relative to the camera and the players, you’ll be more than OK in Bright Sun.
Let’s assume light cloud cover and you need to open one stop.
Let’s assume medium cloud cover and you need to open two stops.
Let’s assume overcast and you need to open three stops.
Let’s assume very overcast and you need to open four stops.
Let’s assume play can be called off, for poor light (five stops).
Now once we get to medium cloud cover – the position of the sun doesn’t matter – so the only scenarios we need to consider are opening up two, three or four stops from the original bright sun being situated behind the camera – so if we need four or three stops open we will be around:
F/5.6~F/8 @ 1/800s @ ISO1600.
And that IMO has used up ALL the leverage and reserve you have in regard to Aperture and Shutter Speed and ISO – the Camera is Maxed at ISO1600- the lens is wide open and / or the Shutter Speed is beyond the limit of being able to regularly freeze an experienced and capable 15year old Athlete sprinting between to a base, much less striking a bat on ball. (I’d want 1/1250s or 1/1000s minimum as “typical”)
So the 70 to 300 will do the job, but you will have your work cut out if it gets cloudy.
My guess is that you want this lens for other uses also and that’s why a zoom is being considered.
If you could get a little closer, then a 70 to 200F/4 would be a safer bet: on the other hand, if it is sunny mostly always where you live – then the F/5.6 lens will do the job at much less cost and give you an extra 100mm of FL.
