The New York Mets have had their fair share of struggles these past few years with three seasons ending with losing records and financial issues off the field. So when MLB Commissioner Bud Selig, Mets owner Fred Wilpon, Mr. Met, and New York City Mayor Michael Bloomberg announced the Citi Field as host of the 2013 All-Star Game — scheduled for July 16, 2013 — of course it made Mayor Bloomberg and Mets fans a little bit giddy.

The 2013 All-Star Game will be the first time since 1964, the inaugral year Shea Stadium opened for the Mets, that the Queens burrough of New York City has hosted. However, New York City hasn't been as far removed — the 2008 All-Star Game was hosted by the New York Yankees during the final season of the old stadium.

Dynamic pricing, or pricing according to market demand, has long been used in the hotel and airline industries. However, the move to sports ticketing, a likely candidate due to the many variables affecting ticket demand, has been slow.

Launched in 2007, Qcue was the first company to provide a dynamic pricing algorithm to be applied to ticket pricing. Its model can be customized for a variety of entities, including promoters and venues, but its work with sports teams has gained the company its trailblazing reputation.

About three minutes after the Baltimore Orioles had rallied to beat the Boston Red Sox 4-3 on the final, crazy night of the baseball regular season last Sept. 28, Evan Longoria's walk-off home run in the 12th inning gave the Tampa Bay Rays an 8-7 victory over the visiting New York Yankees. The results sent the Red Sox home for the winter and the Rays on to the playoffs as the wild card.

Meanwhile, that night in the National League, the St. Louis Cardinals won and the Atlanta Braves lost games that ended about an hour apart. That got the Cards into the postseason as the wild card on their way to an improbable championship. It left the Braves, like the Red Sox, pondering a historic September collapse.

Arizona has a long history of hosting major league spring training camps. Once home to eight teams, a recent building boom of new ballparks has led to half of the 30 major league teams training there. Many now share recently constructed, state-of-the-art facilities.

With another round of Cactus League exhibition games opening this weekend, here's a look at the teams that make their camps in Arizona, starting west and making the way east (Earlier this week, we profiled the 15 teams that train in Florida).
