Edinson Volquez pitched into the eighth inning and Jedd Gyorko and Alexi Amarista each homered, and the San Diego Padres beat the Seattle Mariners 6-2 on Tuesday.

The teams split the brief two-game set in Seattle, but will be right back at it on Wednesday in San Diego for two more games as the "natural rivals" conclude their season series.

Gyorko hit a two-run shot in the fourth inning off Seattle starter Brandon Maurer, his sixth homer of the season. Amarista followed with a solo shot an inning later and the Padres knocked out Maurer (2-7) with three runs in the sixth as they won for just the second time in the past seven games.

Seattle's bats got very little done against Volquez (4-5) and its lineup lost its most potent punch after right fielder Michael Morse had to leave the game in the fifth inning.
