The San Diego Padres bring the league's second-best team ERA (3.53) into T-Mobile Park on Tuesday night, where they'll face a Seattle Mariners squad that's posted solid offensive numbers despite striking out at a high rate this season.
Dylan Cease takes the mound for San Diego looking to keep their strong pitching form intact against Luis Castillo and a Mariners lineup that's been productive at home, setting up an intriguing pitcher's duel between two playoff-contending clubs.
With the Padres sitting as slight road favorites at -130 and the total set at a modest 8 runs, this matchup screams low-scoring affair between two teams that know how to get outs.

Seattle Mariners vs. San Diego Padres preview
The Padres roll into Seattle carrying the second-best ERA in baseball at 3.53, but their offense has been inconsistent, ranking just 22nd in runs per game at 4.2.
Dylan Cease takes the mound for San Diego with solid peripherals, though the Mariners counter with Luis Castillo, who's been dependable all season with a 3.56 ERA and excellent command.
Seattle's lineup has shown more pop with 186 home runs compared to San Diego's 111, but they've also struck out more than any team except two others in the majors.
The bullpen battle could decide this one, as the Padres relievers have been far more reliable with a 73.7% save rate compared to Seattle's struggling 63.0% mark.
Both teams sit in playoff contention with San Diego four games up on Seattle in the standings, making every August game crucial for postseason positioning.
T-Mobile Park's dimensions favor pitchers, which should benefit both Cease and Castillo in what projects as a tight, low-scoring affair between two teams desperate for wins.
