Topps Update is an annual baseball card release from Topps that is typically released after the season has concluded. During the baseball season, players are traded from one team to another and many rookies get their first taste of major league service after September call-ups when the active roster size increases. Also the major league baseball draft is typically held in the summer, again adding players to major league organizations. Finally the playoffs and World Series are held after the majority of baseball card releases have already been distributed, much less designed and printed.
