The San Diego Padres host the Pittsburgh Pirates on Tuesday, August 25, 2026, at Petco Park for a 9:40 PM ET first pitch. Michael King takes the mound for San Diego against Pittsburgh's Paul Skenes in what shapes up as one of the more compelling pitching matchups of the regular season. With a full lineup card in hand for the home side — Fernando Tatis Jr. leading things off through Dustin Harris batting ninth — the Padres will need every edge they can manufacture against one of the most talented young arms in baseball.

Pitching Matchup: King vs. Skenes

Michael King draws the assignment for San Diego, and the right-hander has been a reliable pillar in the Padres rotation. King generates weak contact and works efficiently through lineups, which will be a necessity against a Pittsburgh offense capable of doing damage in bunches. His ability to throw strikes early in counts and avoid the big inning will be the throughline of what the Padres need from him tonight.

On the other side, Paul Skenes is the story. The Pirates right-hander entered the league with historic expectations and has done little to disappoint. His combination of elite velocity and sharp secondary offerings makes him one of the most difficult at-bats in the National League. Petco Park's spacious dimensions may blunt some of the damage Skenes can absorb on his off nights, but this lineup will need to grind at-bats and work counts to have any real chance of breaking through.

San Diego Padres Starting Lineup

• 8. Xander Bogaerts — SS
• 9. Dustin Harris — LF

Keys to Watch for the Padres

Can the Top of the Order Do Damage Early?

Tatis, Cronenworth, and Machado represent San Diego's best shot at making Skenes work. If those three can string together quality at-bats in the first two or three innings and force pitch counts up, the Padres give themselves a chance to see Skenes earlier in his second and third time through the order — where even elite starters tend to be more vulnerable.

King Needs to Limit Traffic

Pittsburgh will put runners on base. The question is whether King can strand them. His effectiveness in high-leverage situations within the game — runners at second and third, two outs — will go a long way toward determining whether San Diego walks away with a win or drops a tough one at home.

Merrill and Campusano as Potential Difference-Makers

Jackson Merrill batting fifth and Luis Campusano seventh give the Padres some depth in the order that can punish a starter who starts to tire or loses command of the strike zone. Skenes will be locked in against the top of San Diego's lineup. The middle and bottom of the order may be where the Padres find their opening.

Prediction

This is a pitcher's duel on paper, and Petco Park is the right stage for it. Skenes is talented enough to keep the Padres lineup quiet for six or seven innings, but King is capable of matching zeros. Give the edge to San Diego at home — a 3-1 Padres win feels right, with King delivering six solid innings and the offense manufacturing just enough against Skenes to get it done.
