Bolt turned his main focus to the 200 m and equalled Roy Martin's world junior record of 20.13 s at the Pan-American Junior Championships. This performance attracted interest from the press, and his times in the 200 m and 400 m led to him being touted as a possible successor to Johnson. Indeed, at sixteen years old, Bolt had reached times that Johnson did not register until he was twenty, and Bolt's 200 m time was superior to Maurice Greene's season's best that year.
