The Giants are absolutely crippled with injuries — Matt Chapman, Daniel Susac, Harrison Bader, Jonah Cox, and multiple pitchers all on the IL heading into this series. Seattle counters with the reliable Logan Webb on the mound while San Francisco is forced to start a TBA pitcher, a massive mismatch in a spot starter situation. Talent and health both favor the Mariners at home, and I trust that edge to cover the -1.5 spread.

Everyone's writing off the San Francisco Giants because of their injury woes, but a 41-55 squad playing with nothing to lose is DANGEROUS — and the Mariners are no world-beaters at 48-49 themselves! The Giants are catching Seattle with Julio Rodríguez on the 7-day IL (head) and Cooper Criswell shelved, meaning both bullpens are leaking and this game is a toss-up that the market is mispricing. Give me the +1.5 with San Francisco — scrappy, overlooked, and ready to ruin somebody's night at T-Mobile Park!

The San Francisco Giants are decimated by injuries heading into this series — Matt Chapman, Harrison Bader, Daniel Susac, Victor Bericoto, and multiple bullpen arms (Randy Rodriguez, Jason Foley, Matt Gage) are all on the IL, gutting both their lineup and pitching depth. Seattle starts Landen Roupp while the Giants counter with a TBA starter, a significant pitching disadvantage on top of their roster carnage. The Mariners are a home favorite at +140 on the run line, offering strong value given the Giants' compromised state.
