Remove Row with Earlier Values in List

I have a list of horses and odds. As the odds of a horse are updated the price is added to the bottom of the list. eg. B2 and B12 in the sheet attached as well as B3 and B 13 etc.

I am chasing a process that will remove the upper most row eg. row 2 and keep row 12 - remove row 3 and keep row 13 and so on.

Any help appreciated.
