The San Diego Padres host the Washington Nationals on Wednesday, September 9, 2026 at Petco Park, with first pitch scheduled for 4:10 PM ET. Walker Buehler gets the ball for San Diego against Washington's Jackson Kent in what amounts to a meaningful late-September regular-season matchup. With a lineup featuring Fernando Tatis Jr., Manny Machado, and Jackson Merrill, the Padres put an experienced, dangerous group in the field. This is a game San Diego needs to take care of business at home.

Starting Pitchers: Walker Buehler vs. Jackson Kent

Walker Buehler draws the start for the Padres. Buehler brings a veteran arm and big-game experience to the Petco Park mound, and the home crowd will be watching closely to see how he commands the strike zone and works through Washington's lineup. Statistical data for Buehler's current-season line is not available at this time, so the focus will be on how he looks Wednesday in real time.

The Nationals counter with Jackson Kent. Kent is a lesser-known commodity, and without available ERA or win-loss figures to lean on, the Padres' lineup will be sorting him out early. That uncertainty can cut both ways — Kent may surprise, or San Diego's lineup depth may expose him quickly.

• 1. Fernando Tatis Jr. — 2B

• 7. Austin Hays — DH

Keys to Watch Wednesday at Petco Park

Tatis Jr. Setting the Table

Fernando Tatis Jr. leads off from the two-bag, and his ability to get on base and put immediate pressure on Kent will set the tone. If Tatis reaches early and Bogaerts works a quality at-bat behind him, the Padres can manufacture trouble before Machado and France even step in.

Machado and France in the Middle

Manny Machado hitting third and Ty France cleaning up fourth gives San Diego a professional, disciplined core of the order. These two don't chase, they drive runners in, and Kent will need to locate his pitches carefully or pay for it.

Merrill's Continued Development

Jackson Merrill hitting fifth in center field is one of the more interesting storylines of this lineup. Merrill has shown he belongs at this level, and his at-bats in the middle of the order will tell you a lot about where this team's ceiling sits down the stretch.

Buehler's Command Early

The game will hinge significantly on whether Buehler is crisp from the first inning. If he commands both sides of the plate and avoids deep counts, San Diego's bullpen stays rested. If he labors early, this game gets complicated fast.

Prediction

The Padres are at home, they have the lineup depth, and they're sending a veteran starter to the mound against a Nationals arm the public knows little about. San Diego controls enough of the variables here to come away with a win. Look for the top of the order to do damage early, Buehler to give the Padres six solid innings, and Petco Park to be loud by the middle frames. Padres win, 5-2.
