Kirby out of his league

Definitely. Just not a top jockey. Back to the sand

Cumani has had a wretched week with nearly all his runners given poor tactical rides/misfortune in running etc etc.

I think Cumani has to either give Kirby a confidence boosting chat or his marching orders, probably the later. He has looked totally outclassed the past week.

Atzeni wasn't any better on Mount Logan...

outclassed I think is spot on
excellent a/w jockey where he is top or near top of pecking order but way down it on turf imo
