The Mariners are extremely tough at home as evidenced by a 41-28 record. George Kirby is Seattle's best pitcher - when he pitches in Seattle. That's the case here. Kirby, who has masterful control, has a 2.94 home ERA.

The Padres have a losing record in their last 11 games. They are starting Yu Darvish, who is trying to work his way back from a groin strain suffered in late May. This is only his second start since May 29. Darvish allowed three runs in 2 2/3 innings against the Tigers in his first start since then last Wednesday.

Darvish also wasn't sharp in his only minor league rehab appearance giving up six runs in 3 1/3 innings against the Reds minor leaguers. Darvish is 38 so his comeback has not been easy.

Offense has been a problem for Seattle. But if you discount a 2-0 loss to the Cardinals, the Mariners are swinging hot bats averaging 9.5 runs in their last four games.
