ARCADIA, Calif. - Talk about an immigration problem. The homegrown players intended for Saturday's $150,000 San Pasqual Handicap at Santa Anita have a right to complain about porous borders.

A fourth is from Brazil, and a fifth, though foaled in Kentucky, did his racing in England and the Middle East until his people wised up and figured America was easier pickings.
