Field sizes holding up despite weather Hot weather normally sparks a dramatic reduction in the field sizes for Irish races, but the current heat-wave has had no affect on tomorrow's National Hunt fixture at Cork. 119 horses are set to line-up for the seven races including a maximum field of 24 plus 2 reserves for the Follow Us On Twitter Maiden Hurdle. The going at Cork is described as Good to Firm. The track was watered this morning and will be watered twice more before racing commences at 5.55pm tomorrow evening. The first race is the feature event, the Dermot Casey Tree Care Hurdle with a prize pool of €20,000. Unusually, course and distance winner, Oilily is the only member of the seven runner field to have competed over hurdles last time out. All the others come here on the back of Chase runs.
