The best general sports app available today for BlackBerry 10 is theScore. It currently offers live coverage of sports including football (NFL), basketball (NBA, NCAA), hockey (NHL) and soccer (EPL / Premier League, UEFA Champions League), and the developer says more sports will be supported soon. theScore also provides, box scores, player stats, league leaders, betting odds, game previews, recaps, top stories, schedules and league standings. The app's UI leaves something to be desired, and some major sports leagues are currently missing, including Major League Baseball, but theScore is still a worthy app for BlackBerry-toting sports fans.
