Covers Preview -
The Arizona Diamondbacks have taken over first place in the National League West with little resistance from the Miami Marlins, who aren't scoring much these days. Arizona will try to complete a three-game sweep and win its fifth straight contest when it visits Miami on Sunday. After recording 16 hits in Friday's 9-2 victory, the Diamondbacks needed only four to back Brandon McCarthy's three-hitter in Saturday's 1-0 win. The Marlins have lost a season-high seven straight.
