ATLANTA - Jim Riggleman set the pace for his first game as Seattle's manager by scheduling batting practice three hours earlier than normal.
The extra swings must have helped.
Jose Lopez drove in four runs with three hits, including a three-run double in the eighth, and the Mariners enjoyed one of their best offensive games of the year in beating the Atlanta Braves 10-2 on Friday night.
The Mariners matched their season high with 15 hits, including a season-high eight doubles. They scored five runs in the eighth, also matching their high mark for an inning this season.
Adrian Beltre was 2-for-4 with three RBIs.
Riggleman was promoted from bench coach when John McLaren was fired Thursday morning. Riggleman managed his first game since Oct. 3, 1999, the end of his five-year run with the Chicago Cubs.
Ryan Rowland-Smith (1-1) gave up no hits and one walk in 12/3 scoreless innings as the second reliever behind starter Erik Bedard.
Bedard left with back spasms in his right side after three scoreless innings, giving up only two hits. The Mariners were without fill-in closer Brandon Morrow, who remained in Seattle while also suffering from back spasms.
Jorge Campillo (2-2) gave up four runs on eight hits, including five doubles, in 61/3 innings. Will Ohman gave up five runs while recording only two outs.
Roy Corcoran, who relieved Bedard, walked Chipper Jones and Mark Teixeira in the fourth. Jones scored on Omar Infante's single to center. Corcoran gave up another hit to Brian McCann, loading the bases, but Jeff Francoeur hit into a double play to end the inning.
Seattle tied the score 1-1 in the sixth when Lopez doubled to left and scored on Beltre's double to right.
Seattle took the lead with three runs in the seventh. Pinch-hitter Jeremy Reed's double to left drove in Willie Bloomquist with the go-ahead run. Lopez and Raul Ibanez added run-scoring singles.
The Mariners put the game away in the eighth. Lopez hit a bases-loaded double to left to drive in three runs. Ibanez added a run-scoring double.
Kelly Johnson's double in the eighth drove in Yunel Escobar for Atlanta's second run.
