The Los Angeles Sparks, a two-time WNBA champion and 10-time playoff maker, set out to wow fans with sky-high jumps and nimble-fingered ball handling. After averaging 20.6 points per game in 2010, forward Candace Parker looks to ascend the league's list of scoring leaders, along with teammate Tina Thompson, who finished last season with a stellar 16.6 PPG average. Centers Jantel Lavender and Courtney Paris will guard the basket from nesting owls.

In addition to hosting the Sparks' back-to-back championships in 2001 and 2002, the Staples Center has earned good karma for its eco-friendly practices, shrinking its carbon footprint with 1,727 solar panels and a slew of energy-saving light bulbs. Lower-level-center-court seats provide an up-close view of the tip-off, and lower-level-corner tickets let fans play foam-finger fetch with Sparky, the team's lovable canine mascot and California state senator.
