Base awards mandatory?

[Forest Ump]

It's a four base award. If he stopped at third I would treat it the same as a hit batsman. He doesn’t get to chose whether to go to a base or not. If he abandoned the bases, it would simply be an out. No base hit. Not a scoring expert but I think that's right.

7.05 Each runner including the batter-runner may, without liability to be put out, advance—
(a) To home base, scoring a run, if a fair ball goes out of the playing field in flight and he touched all bases legally; or if a fair ball which, in the umpire’s judgment, would have gone out of the playing field in flight, is deflected by the act of a fielder in throwing his glove, cap, or any article of his apparel;

He'd get the triple.

This has been gone over before and the consensus is that if he does not advance to the awarded base he has abandon it and will be called out. This occurred in a walk-off home run with two outs that was nullified because of this and they had to go into extra innings. I can not remember if it was FED or OBR rules that was used.
