Shelly-Ann Fraser-Pryce fixes wig mid-race but still qualifies in worlds 200m

• Jamaican crosses line in second in women's 200m heat
• Big names including Dina Asher-Smith qualify for semis

World 100m champion Shelly-Ann Fraser-Pryce had to fix her wig halfway through her women's 200m heat as she suffered a surprise defeat to Niger's Aminatou Seyni.

The incident occurred as the Jamaican flew around the bend and felt her electric turquoise wig slipping - forcing her to reach her right arm upwards and take a second or so to adjust it. However she still finished in 22.26sec as she qualified easily for Tuesday's semi-final.
