Reigning World 200m champion Usain Bolt will defend his title in Moscow at the 2013 IAAF World Championships and will look to regain the 100m crown he lost to team-mate Yohan Blake in Daegu two years ago.Blake is unable to accept his wildcard entry in the 100m as he has been forced to miss the rest of the season due to injury. But Bolt’s victory in the 2012 Diamond Race means he gets an automatic entry for the shorter sprint, allowing Jamaica to send four athletes in both the 100m and 200m.Elsewhere on the 45-strong team, Nickel Ashmeade will also be doubling up, while Kemar Bailey-Cole and Nesta Carter contest the 100m. Olympic bronze medallist Warren Weir will be a medal favourite in the 200m.Two-time Olympic 100m gold medallist Shelly-Ann Fraser-Pryce is also contesting both the 100m and 200m in Moscow.As ever, the relay teams are strong and the Jamaican men are hopeful of retaining their 4x100m title. Jamaica won medals in all relay events at the last World Championships and will be keen to do so again in Moscow.IAAFJAMAICAN TEAM FOR MOSCOWMen 100m: Nickel Ashmeade, Kemar Bailey-Cole, Usain Bolt, Nesta Carter 200m: Ashmeade, Bolt, Jason Livermore, Warren Weir 400m: Javere Bell, Javon Francis, Rusheen McDonald 110m Hurdles: Hansle Parchment, Andrew Riley, Dwight Thomas 400m Hurdles: Leford Green, Isa Phillips, Annsert Whyte Long Jump: Damar Forbes Shot Put: Raymond Brown, O’Dayne Richards 4x100m Relay: Ashmeade, Oshaine Bailey, Bailey-Cole, Bolt, Carter, Livermore, Weir 4x400m Relay: Bell, Francis, Omar Johnson, Akheem Gauntlett, McDonald, Edino SteeleWomen 100m: Sheri-Ann Brooks, Schillonie Calvert, Shelly-Ann Fraser-Pryce, Kerron Stewart 200m: Fraser-Pryce, Patricia Hall, Anneisha McLaughlin 400m: Hall, Stephanie McPherson, Novlene Williams-Mills 800m: Natoya Goule 100m Hurdles: Andrea Bliss, Danielle Williams, Shermaine Williams 400m Hurdles: Danielle Dowie, Kaliese Spencer, Ristananna Tracey, Nickiesha Wilson Long Jump: Francine Simpson Triple Jump: Kimberly Williams 4x100m: Brooks, Calvert, Fraser-Pryce, McLaughlin, Natasha Morrison, Carrie Russell, Stewart 4x400m: Christine Day, Hall, Anastasia Le-Roy, McPherson, Rosemarie Whyte, Williams-Mills
