Luis Arraez homered twice and Jacob Stallings had two doubles, the second a go-ahead line drive with the bases loaded in the seventh, and the Miami Marlins beat the NL East champion Atlanta Braves 9-6 on Friday night. In their first game since winning the division title Wednesday, the Braves lost star slugger Ronald Acuña Jr. after 7 1/2 innings because of right calf tightness. Acuña went to his position after grounding into a double play to end the top of the eighth but left before a pitch was thrown in the bottom half.
