It depends, a team might have reserved baseball jerseys from maybe 1984 or 1968 for e.g. So maybe about 5-7 jerseys(3 for minimum, away jersey, home jersey, pre season jersey). In other words, baseball players have around five to seven jerseys. They always have at least three; home, away, and alternate (preseason).
