Kyle Greaux, on the anchor leg, had just enough in him to help T&T edge Jamaica at the line for second place in the final of the men's 4x100 metres relay at the North American, Central American and Caribbean (NACAC) Track and Field Senior Championships, on Sunday at the Freeport Stadium in Grand Bahama in the Bahamas.

On the third and final day of the senior meet, Greaux led in a team that included Jerod Elcock, Eric Harrison Jr and Asa Guevara to seal T&T's second medal, a silver.

The other, also a silver, was won by two-time Olympic medallist Keshorn Walcott in the men's javelin event, on Saturday night.

In the sprint mens' relay finale, the eventual third-placed Jamaica team of Ackeem Blake, Andrew Hudson, Kadrian Goldson and Jahzeel Murphy clocked the same time (38.94) as the T&T quartet. However, theÊlocal team's time (38.931) was two-thousandth of a second faster than the finishing time of the Jamaicans (38.933).

The Caribbean teams finished behind the American foursome of Lawrence Johnson, Brandon Carnes, Isiah Young and Kyree King, who sprinted to gold in a time of 38.29.

Minutes earlier, the T&T sprint women's team of Khalifa St Fort, Mauricia Prieto, Reyare Thomas and Shaniqua Bascombe, running in that order, missed out on a medal after placing fourth with 43.81.

Cuba placed fifth with a 44.46-clocking.
