Because of the weather, the Phoenix area has many outdoor sports venues. The Fiesta Bowl (college football) is held in Arizona State's Sun Devil Stadium in Tempe. There are also many professional baseball teams that hold their spring training near Tempe. The Anahiem Angels use the Tempe Diablo Stadium and the Oakland Athletics use the Phoenix Municipal Stadium by Papago Park. Of course, ASU has all the usual outdoor sports that a large university normally supports.
The Phoenix Suns are the NBA's better teams and the most fun team to watch. They play run-and-gun "small ball" with Steve Nash, Shawn Marion and Amare Stoudamire leading the way. Good tickets may be hard to get though.
