The Seattle Mariners host the San Diego Padres at T-Mobile Park with both teams fighting for postseason positioning, as the NL West-leading Padres (74-57) look to pull away in their division while the Mariners (70-61) cling to the final AL wild card spot despite winning just two of their last 10 games.
Starting pitchers JP Sears and Bryce Miller have both struggled this season, setting up what could be a high-scoring affair between two lineups that have shown recent offensive life.
With the Padres' Manny Machado and Fernando Tatis Jr. squaring off against the Mariners' Cal Raleigh and his league-leading 47 home runs, this matchup offers plenty of betting value in a crucial late-season clash.

Seattle Mariners vs. San Diego Padres preview
The Padres arrive in Seattle sitting pretty atop the NL West at 74-57, but they'll face a Mariners team desperately clinging to that final AL wild card spot after managing just two wins in their last ten games.
JP Sears takes the mound for San Diego carrying a concerning 4.15 expected ERA and having surrendered 69 runs across 129 innings, though his offense has awakened with 30 runs over their last six contests.
Seattle counters with Bryce Miller, who's been even shakier with a bloated 5.63 expected ERA and opponents tattooing him for hard contact at a 48.2% clip in his 53 innings of work.
The Mariners' power surge has been led by Cal Raleigh's monster 47 home runs, while the Padres have gotten steady production from Manny Machado (.292/.354/.482) and recent trade acquisitions like Ryan O'Hearn providing crucial depth.
With both starters struggling to keep runs off the board and Seattle needing every possible win to stay in playoff contention, this late-August clash could turn into an offensive showcase under the T-Mobile Park lights.
The Mariners' home crowd will be hoping their team can snap out of this recent funk, but the Padres arrive with momentum and the luxury of playing with house money as division leaders.
