Good shots. Excellent action and isolation from the background. As others have pointed out, your results are not bad for these conditions.
How do I deal with harsh light? Well, first I remember what a pain it was to shoot sports at around EV 7 in poorly lit gyms and arenas! :smile: Then I try to expose for the important highlights, let the whites fall where they may, and hope for enough shadow detail. You have to accept some blown highlights, and just try to avoid sharp transitions to featureless areas on skin, faces, etc. Choosing camera angle to avoid, as much as possible, direct reflection from bright areas can help, in theory. However, achieving this in practice is usually impossible since shooting position is dictated by the action, background and available access.
This is one situation where negative film was superior, with larger dynamic range and smoother toe and tail transitions. However, even in the old days, you could capture considerably more dynamic range on a negative than it was possible to display in a print.
Post processing can also help. If you are shooting in raw, you can underexpose a bit and bring back shadow and midtone levels using a curve similar to the hdr mode in RML. Alternatively, you can use D-light in NX or highlight/shadow in PS to help tame the contrast.
