Looking at Dargo's Exif photo data.
f/5.8 @ 89mm (350mm equiv you were fully zoomed in f4.9 was the max aperature fully zoomed in) Iso speed 50, shutter 1/100. Wow!! you really got lucky with this shot Dargo. Your camera was doing the same thing as
California's. It thought you were taking a landscape shoot instead of an action photo. 1/100 shutter is on the brink of blurred action. You can tell by the low iso speed it picked that it thought it was doing a landscape shot.
f/5.8 at 350mm equiv... is great however... and your lens helped a huge amount with that shot even though your camera's AUTO setting was fighting you all the way.
Manually setting it to f4.9, iso 200, shutter 1/500 would have given you the same exposure and would have been SI quality.
