I will say that when I played club soccer, I would cross myself before the start of each game (my mother’s side of the family is Eastern Orthodox, and even though I’ve long since converted to mainline Protestantism, the habit has stuck with me), but I didn’t really do it out of a sense of praying to God to intervene on my behalf in my sport, I did it as a means of centering and focusing myself. In any case, I’d be willing to bet that sports are somewhere around “overconsumption of cilantro” on God’s list of concerns.
