5. Washington Nationals

Average ticket price: $35.24

Change from 2012: +15.4%

Of course, some teams just get a small taste of glory and start seeing dollar signs. After the Nationals' first-ever playoff appearance last year -- a 3-2 loss to the Cardinals in the division series -- the Nats jacked up ticket prices and started selling 16-ounce beers for $8.25 a pop. In fairness, the Nationals play in a major market that the Montreal Expos were moved to with the understanding that they'd be able to cash in on it. With young stars such as Bryce Harper and Stephen Strasburg, owner Ted Lerner and Nats fans are optimistic about the days ahead. That's great, especially considering teams with one winning season in eight years usually don't get to jack up prices at will.
