Here's a look at the pitching matchups for the series between Seattle and Detroit: Luis Castillo is coming off arguably his best start of the season. He struck out eight and allowed two hits in seven innings against the Pittsburgh Pirates on July 5. It was his fifth quality start in his last seven outings.

Seattle Mariners catcher Cal Raleigh clubbed two more home runs in a 12-3 win against the Detroit Tigers on Friday night, including a grand slam to help break the game open in the top of the ninth inning.
