I / Kingstown (St Vincent) March 8, 2007Adam Gilchrist believes aggressive batsmen like himself won't have it all their own way at the World Cup despite fellow Australia opener Matthew Hayden's prediction that a landmark score of 500 runs in a one-day international innings is now in sight.Australia wicket-keeper Gilchrist, one of the most dynamic batsmen in the modern one-day game, only arrived in the West Indies on Monday following the birth of his third child.But having been a spectator for world champions Australia's first warm-up match, a 106-run win over Zimbabwe, Gilchrist is now set to face old rivals England in his side's second and final practice match here Friday.The ground is typical of many that will be used in the tournament proper in that its short boundaries are an open invitation to renowned hitters such as Gilchrist, who in 257 one-day international has scored 8,585 runs, including 14 hundreds, at an average of nearly 35.62.However, the slow, low pace of the Arnos Vale pitch has made strokeplay difficult and the surface could provide a guide for things to come at this World Cup, even though the nine highest totals by a team winning after batting second in limited overs international history have all been achieved since the turn of the century."Scores are becomingly increasingly more and more and it's mind-blowing, some of the batting that's going on," Gilchrist told reporters during Australia's net session at Sion Hill here yesterday."Bowlers across the world are copping a pounding for it. I don't know where it will end. Anything is possible but I am not sure we will see 500 just yet."
