Kiwi Tom Walsh became the first man to win back-to-back shot put titles in the IAAF Diamond League, winning at the AG Memorial Van Damme with 22.30m.
Held in the Place de Brouckere in Brussels city centre on the eve of the main competition, the world champion's winning effort came in the opening round and withstood challenges from not just himself but seven other men in the field with 22-metre PBs.
Olympic champion Ryan Crouser went into second place with his opening effort of 21.85m, but was relegated to third when Brazil's Darlan Romani sent his shot out to 22.15m.
Crouser improved to 22.08m in round three, making this just the fourth competition in history in which three men have thrown beyond 22 metres, but it wasn't enough to move up the leaderboard.
Walsh responded with two more throws beyond the farthest-placed white line, landing 22.07m in round four and 22.05m in round five.
