SEATTLE (AP) - Matt Stairs cracked a long solo homer off the facade of the second deck, San Diego starter Clayton Richard wiggled free from the few jams he faced, and the Padres held on for a 2-1 win over the Seattle Mariners on Saturday night.

A night after the teams combined for 23 runs to open interleague play, both sides struggled to mount much offense.

Stairs came through in the fourth off Seattle starter Ian Snell for his first homer of the season. Facing a 2-2 count, Stairs lined a 412-foot shot off a Las Vegas advertisement in deep right field.
