There were mixed fortunes for the Caribbean men in the 400m semi-finals on day four of the IAAF World Athletics Championships in Budapest on Tuesday.

Antonio Watson was first up and set the track ablaze with a massive personal best 44.13 to take semi-final one over the likes of South African world record holder Wayde Van Niekerk and American Vernon Norwood.

Norwood ran a personal best of his own with 44.26 for second while Van Niekerk ran 44.65 in third and Jereem Richards ran 44.76 in fourth.

Van Niekerk made it through to the final as one of the fastest losers while Richards was just beaten out Norway’s Havard Bentdal Ingvaldsen who ran 44.70 in heat two.

Great Britain’s Matthew Hudson Smith won the second semi-final in a personal best, British and European record 44.26 ahead of 2011 World Champion Kirani James who ran 44.58.

Unfortunately, reigning Olympic Champion Steven Gardiner looked set to book his spot in the final before pulling up injured while leading with about 100m to go in the third semi-final.

The race was eventually won by American Quincy Hall in 44.43 while Jamaica’s Sean Bailey also made it through to the final with 44.94.
