MLB: Seattle 10, Atlanta 2

ATLANTA, June 20 (UPI) -- A four-RBI performance from Jose Lopez Friday helped boost Seattle to a 10-2 bashing of Atlanta in the debut of Mariners Manager Jim Riggleman.

Riggleman moved up from bench coach when John McLaren was dismissed on Thursday after less than a year on the job.

Seattle broke a 1-1 tie with a three-run seventh, during which Lopez singled in a run. He then delivered a three-run double in the eighth, part of a five-run inning.

That outburst made a winner out of Ryan Rowland-Smith (1-1), the third Seattle pitcher of the game who did not allow a hit in 1 2/3 innings.

Seattle piled up 15 hits in the opening contest of a nine-game road trip that follows a 1-5 home stand.

Atlanta has lost just 12 of 37 home games this season. Jorge Campillo (2-2) suffered the setback in his eighth major league start. He gave up four runs on six hits in 6 1/3.
