San Francisco @ Seattle preview

Last Meeting ( Jun 17, 2015 ) San Francisco 0, Seattle 2

The San Francisco Giants are experiencing a deep slumber and have lost six of their last seven games entering Thursday's contest against the host Seattle Mariners. San Francisco was shut out for third time during the swoon while losing 2-0 to Seattle and Felix Hernandez on Wednesday.

The Giants had just four hits and only two runners moved into scoring position as they continue to struggle offensively. San Francisco has scored two or fewer runners five times during the woeful stretch and trail the first-place Los Angeles Dodgers by 2 1/2 games in the National League West. Seattle split two games with the Giants in San Francisco before recording the victory Wednesday as Austin Jackson delivered an RBI triple and Robinson Cano added a run-scoring double. Mariners slugger Nelson Cruz is 0-for-14 over the last four games and hasn't homered since May 27.
