The Los Angeles Sparks have been on roll lately, battling their way back to just below .500 after a slow start to the season. Los Angeles has won four of its past five games and a big reason why is the play of All-Star Nneka Ogwumike and free agent signee Liz Cambage. The 6-foot-8 Australian struggled for most of June but has playing better during the Sparks’ recent run. She has scored in double figures the past four games — something she hadn’t done once since May 31. The Sparks moved up three places to sixth in the AP WNBA power poll this week.
