radio tips are done by race callers. Some are good at form, and some are poor. In this case you just got a poor tipster.

Certain tipsters give ranking to special features like time of spell, barrier trials, last run time, etc.

Apart from Race 6 he seemed to stay clear of resuming horses. Also the horse was in a wide barrier which may have impacted his thoughts. There are so many reasons he could have ruled out the horse it is almost useless trying to work it out.

Also looking at the horses 3 previous runs it likes to run from the front and barrier 12 is not a great place to be for a pace setter.

There just my thoughts on why it could have been dismissed. There are a number of reasons to include it as top selection though which includes it has ben close to the front most races even from a wide barrier and has finished in or near the money, Its the only horse I could see that looked like it had the (limited) class needed to win the race.

Good Luck.
