A STRIKE rate of 50 per cent is unheard of in Hong Kong but that is exactly what Walter Swinburn can boast as he goes into this afternoon's International Cup and Bowl meeting. Five winners from just 10 rides and there could be more as the man for the big occasion has another choice book of rides. Swinburn is in demand throughout the day, bar the International Cup. His best chances look to be in the first two events with Ivan Allan's pair Mighty Mighty and Explorer and in the last with Neville Begg's Deerfield. Mighty Mighty, in particular, has been found an uncompetitive event by master trainer Allan with only Lucky Century and Lionheart looking to be realistic dangers. Explorer moves up in distance from 1,200 metres to a mile in the second which should suit. Deerfield is another who looks set to improve now that he steps out over farther. He has shaped encouragingly over 1,200 metres and then a mile and now looks in peak condition for the 1,800-metre final event.
