Has anyone else noticed the high percentage of pros on both the men's and women's tours who conspicuously wear a cross around their necks? Several players (Juan Martin del Potro probably being the most conspicuous) make a point of crossing themselves and kissing their fingers up to the sky when they win. Djokovic does both of these things, and has even been awarded, to great public fanfare, the highest distinction in the Serbian Orthodox Church. It would be interesting to do a study on how many athletes are atheist or non-religious and where they tend to come from (my guess is Northern and Western Europe). Looks like most of the Christians come from the U.S. and second- or third-world countries. Anybody know about the beliefs of players from Muslim or other non-Christian countries (mostly these would be in Asia)? I don't recall noticing other ostentatious displays of religion on the pro circuit other than Christian ones. This just got me wondering about how many pros might be Buddhist, Muslim, atheist, or other religions.
