The Seattle Mariners defeated the Los Angeles Angels 7-2 last night when the teams opened a four-game set at Safeco Field. The M's recorded a season-high 19 hits while the Halos had eight, but I expect both teams to struggle at the plate tonight in what should be a low-scoring contest. Here are my keys to the game: 1. Pitching - The Angels will hand the ball to Hector Santiago (5-4, 2.40 ERA) who's undefeated in his last three starts conceding just a total of two runs on eight hits and four walks over 20 innings of work, seven innings of one-run ball against the M's on June 28 included. The Mariners will counter with Mike Montgomery (4-2, 1.62 ERA) who's been terrific over his last three starts as well, conceding only one earned run over 23 2/3 frames. Look for the bats to quiet down tonight and this game to stay UNDER THE TOTAL.
