San Diego is clinging to the NL's final wild-card spot with Arizona breathing down its neck, and San Francisco would love nothing more than to be the team that trips them up.
Neither club has named a starter for Saturday's game at Oracle Park, and both rotations are running thin this deep into September. San Diego has been without Joe Musgrove and Lucas Giolito all year, while San Francisco has already lost Adrian Houser, Carson Whisenhunt and Trevor McDonald for the season. Whoever gets the ball, it won't be from a position of pitching depth on either side.
The bigger story in San Francisco is the length of the injury list around that rotation. Willy Adames and Matt Chapman are both out for the year on the infield, and the bullpen has been stripped down by injuries to Rowan Wick, Randy Rodriguez, Hayden Birdsong and Sam Hentges. That's forced manager Tony Vitello to lean on younger, less-tested arms and lineup pieces down the stretch, even while the club has quietly won 2 straight.
San Diego and San Francisco open this set Friday, so nothing about who's carrying momentum into Saturday is settled yet. The Padres arrive off wins over the Yankees and the Nationals, the Giants off a stretch against the Mets and Cardinals, and both bullpens will look different by the time first pitch at 1:05 PM PT rolls around depending on how that opener goes.
San Diego's relief corps is the thing to watch. Jeremiah Estrada, Jason Adam and Bryan Hoeing are all on the injured list, which thins out a bullpen the Padres are leaning on hard in a playoff race. Gavin Sheets, sidelined with a foot sprain, is trending toward a return around mid-September and would give the lineup a needed bench bat right as the wild-card chase tightens.
For the Giants, there's no such urgency — just an opportunity to play spoiler and get a look at what they have heading into next year. For the Padres, every game between now and October carries weight with Arizona sitting within half a game of that last wild-card spot. That contrast in stakes is what makes this series worth watching even with the standings so lopsided.
