One, Two, Three Years You're Out At The Old Ball Game

For a while there has been a prevailing theory in the sports world that it's worth it to lock a budding star into a long-term contract before his value escalates. Concerned about the ever-increasing salaries in Major League Baseball, the New York Mets signed Mike Piazza to a seven-year deal. Okay, Mike Piazza isn't Jewish; this article won't be relevant to him. But what about Shawn Green? In 1999, he inked a six-year deal with the Dodgers worth $84 million. He is known as the best Jewish baseball player since Sandy Koufax. Although irreligious, Green made waves by honoring his commitment not to play baseball on Yom Kippur. After playing 415 consecutive games, he sat out a game on the evening of September 26, 2001-Yom Kippur.
There are serious issues about playing professional baseball on Shabbos. Playing baseball falls under the category of uvda d'chol; it is a tremendous zilzul of Shabbos to play baseball publicly. There also might be an issue of s'char Shabbos. One cannot get paid for services performed on Shabbos, even if the work performed does not, in and of itself, violate Shabbos. (There are permissible ways to structure a contract to get around this problem.)
