Las Vegas does not have major-league sports, although the metropolitan population is as large or larger than many cities that have them. The two major reasons are concern about legal sports betting and competition for the entertainment dollar, both of which which Las Vegas has in abundance.
The city currently has two minor league sports teams, baseball's Las Vegas 51s of the Pacific Coast League (the AAA farm club of the Toronto Blue Jays), and hockey's Las Vegas Wranglers of the ECHL (an affiliate of the Calgary Flames).
In the past, the city had teams in the Canadian Football League, the XFL and the Arena Football League. There was recent mention in the local media that the San Diego Chargers of the NFL may be considering Las Vegas as a relocation destination.
There is speculation that the completion of a new arena (under construction and expected to open in 2010) will bring teams from the NBA and NHL.
The city is reportedly on the short list of Major League Soccer for an expansion franchise in the near future.
There have also been contacts between city officials and several Major League Baseball owners regarding relocation.
The ownership of the Florida Marlins held a widely-publicized meeting with Mayor Oscar Goodman in the winter of 2004. The city was a strong candidate to be the new home of the Montreal Expos, who eventually became the Washington Nationals.
It was reported that the guarantee of a new stadium built entirely with public funds swung the balance in Washington's favor. Major League Baseball will hold their 2008 winter meetings in Las Vegas, and it is a foregone conclusion that a strong case for a team will be made on behalf of the city.
High profile limited-duration sporting events have been successful.
Las Vegas hosted the 2007 NBA All-Star Game. The NASCAR Sprint Cup series has drawn up to 165,000 fans.
Las Vegas also hosts a significant number of professional fights. Many of these fights (such as those in MMA's UFC) take place near downtown or on the Strip in one of the major resort/hotel/casino event centers. Mandalay Bay is frequently a top contender as a venue for the UFC.
The National Finals Rodeo has drawn thousands of fans to the city since 1985, and a contract extension was signed in 2005 keeping the event in Las Vegas through 2014.
The NBA Summer League is currently held in the city, and the USA Olympic basketball team trained in the city in 2008.
The University of Nevada, Las Vegas competes in NCAA Division I in men's and women's sports. UNLV is a member of the Mountain West Conference. The College of Southern Nevada also has an athletic program, with significant success in baseball at the community college level
There are strong athletic programs at many Las Vegas high schools, with a number of players in several sports going on to major colleges and professional careers as athletes.
