How to prepare a baseball cap for wearing?

Since the 1970s, the eight position players for each team who take the field initially have been voted into the game by fans. The remaining position players and all of the pitchers on each league's roster were, for a large number of years, solely at the discretion of that team's manager. In 2004, however, MLB instituted a system where some reserves and pitchers were selected by a vote of MLB players, and some were selected by the manager after consulting with the Commissioner's Office. Each person is allowed to vote 25 times. By MLB regulation, every team in the majors must have at least one designated all-star player, regardless of voting. This rule exists so that fans of every team have a player to watch for in the All-Star Game. The 2007 All-Star Game will be played in San Francisco at AT&T Park.
