I cropped the images a little. The images are very under-exposed, so there is little room for improvement.
Spot metering was used with no Exposure Compensation on the two images below
I adjust the Highlights all the way down to -100 to get the colors to begin to show.
I can't see from EXIF if DRO was used, it does affect the RAW files and gives more latitude to widely varying lighting conditions
This is from first image screen shot from CaptureOne settings:
This screenshot shows CaptureOne settings for the following image. I had to adjust color on the basketball as the highlights were blown out.
I am certain that others could probably edit these much better but this should give you a starting point
My recommendation when taking shots like this is :
1. Turn on DRO, as mentioned above it DOES affect RAW files and gives more latitude on color correction etc.
2. Use AEL , focus on an area that is mid-lighting and toggle AEL this may help to give a median baseline for lighting, then recompose, focus and take the shot.
