Irish Champion Stakes Betting Update The Irish Champion Stakes market has developed into a ´weather watch´ with punters reluctant to show their hand before hearing whether rain has arrived at the south Dublin track. Interestingly, it is this, and not the jockey merry-go-round that is having the biggest impact on the ante post market. Motivator´s trainer Michael Bell is due to walk the course later today but in the absence of rain on Tuesday - and with little sign of any on Wednesday- his star colt is still freely available at 6-1 on Betfair´s ante post market. The Irish Met office are predicting rainfall of between 30mm and 60mm across a wide band of the country, which, if reaching Dublin, should see Motivator and Grey Swallow line up alongside Azamour et al on Saturday afternoon.The main Betfair market moves on Wednesday morning are as follows:Azamour´s price lengthens slightly to 1.8 (4-5). Motivator´s price continues to fluctuate around the 7.0 (6-1) mark. News that Kevin Darley will ride should he take his chance. Money for Oratorio as the current good to firm ground would be ideal for the King George winner. He´s currently available at 6.5 (11-2).Grey Swallow drifts on Tuesday but is supported back into 10.0 (9-1) on Wednesday morning. Ace and Alexander Goldrun both drift out to 28.0 (27-1). Both have alternative engagements on the day.Norse Dancer drifts out to 33.0 (32-1).
