Usain Bolt and Tyson Gay will race when Jamaica and the United States field teams in the 4x100 meter relay at the Diamond League meet in Zurich.
Organisers of the August 19 Weltklasse meet said on Thursday that Olympic and world champion Bolt will anchor a Jamaica team including Mario
Forsythe, Yohan Blake, and Marvin Anderson. Gay, the second-fastest man in history behind Bolt's record of 9.58 seconds, heads a US lineup featuring Walter Dix, Wallace Spearmon and Trell Kimmons.
Bolt and Gay are skipping the individual 200 at Zurich, which splits the Diamond League finals with Brussels the following week. Bolt, Gay and former world record-holder Asafa Powell of Jamaica will race the 100 at Stockholm's Diamond League meet next week.
