Mexico will not win a lot of medals, maybe 3 or 4 like last time. Still I expect that in Beijing they can catch a gold. The sports in which the country can obtain medals are:
Tae Kwon Do (1 or 2, gold, silver or bronze)
Diving (1 or 2, silver or bronze)
Athletics (1 or 2, silver or bronze)
Canoeing (1 bronze)
Cycling (1 bronze)
Archery (1 bronze)
Sailing (1 bronze)
Football (if they qualify)
