Blackburn Rovers striker Jason Roberts scored as Grenada drew their home leg of the CONCACAF region World Cup qualifying against Costa Rica.

Roberts put Grenada, who are ranked 143rd in the world, 2-0 up in the first half, adding to Patrick Modeste's earlier strike.

However Armando Alonso scored before half-time to pull one back for Costa Rica, and Wisla Krakow defender Junior Diaz equalized for the visitors in the 75th minute.
