EUGENE, Ore. (Reuters) - Reigning 200 metres champion Noah Lyles said having his younger brother as teammate makes the world championships even sweeter, as the international meet kicks off Friday in Eugene, Oregon.

The 24-year-old American was flying solo when he picked up bronze in Tokyo and said he is far happier having Josephus, who is in the U.S. 4x100 metres relay pool, by his side.
