Mr Shatner,
They keep their stage name like actors, because they are "known as".
Sometimes they are hyphenated, but usually they stick to their maiden name.
Even more interesting is that in the trotting game so many are related to one another in some natural or in-law capacity.
It's rife, they all seem to marry like actors.

In case Jessica Valas doesn't show I'll add as well

Talia Rodder

Sorry forget that. We'll add another WA rider instead

Katariina Aho

Two of our jockeys go up against each other at Bordertown today. I feel a winner coming on. Bit worried about adding the extra rider as its never a good thing to change your test while its running.

Bordertown R1. There's something you don't see every day. Who's the odd man out?

Well that's about as clear a tip as you get from me. Hope somebody profited. ;)
