As shown in the histogram, it is significantly underexposed, which increases the noise. The softness is from a shutter speed that is too slow. 1/180 is much too slow to freeze action; you should aim for 1/500 minimum, even with these young athletes. Raise the ISO to solve both problems.
Raising the ISO will only solve the problem with motion blur. While there is almost always going to be some motion blur in shots like this, and some benefit from using a faster shutter speed, I disagree that it is the main reason for the softness here, though.
Regarding noise, Rising the ISO will not solve any problems. The noise problem with an underexposed image is almost exaclty the same as using a higher ISO and exposing higher up on the histogram. The photometric exposure will be the same in both cases. As long as we don't get more light in, we will not get less midtone noise at these ISO values.
In addition to that, raising the ISO to get a better looking histogram will not give a better shutter speed. If you raise the ISO both to get a better looking histogram and a faster shutter speed, you have to raise the ISO two stops and actually get more noise.
