Doubles standout Daniel Nestor will miss Canada’s Davis Cup tie against Mexico due to an inflamed Achilles tendon. Despite this and the fact that the tie will be played on clay, Canada will be favored. Mexico’s top player, Santiago Gonzalez, is in a feud with captain Jorge Lozano and won’t play, and Canada features the surging Milos Raonic. Mexico doesn’t have a player ranked in the Top 400 on its team.—Matthew Cronin
