Mason Miller activated from paternity list, throws scoreless 7th in NLDS Game 4

Mason Miller became a father, then became a problem for opposing hitters again — all within the span of a single postseason series. The Padres closer was activated from the paternity list and pitched a scoreless 7th inning in NLDS Game 4, per MLB.com's Jessica Camerato.

What happened

Miller had been placed on the paternity list ahead of NLDS Game 3, making him unavailable for that contest. One day later, he was back on the mound. Camerato reported that Miller was activated and delivered a clean 7th inning, giving San Diego's bullpen a significant piece back at a moment when the relief corps had been navigating some turbulence.

The paternity list is one of baseball's more quietly civilized institutions — a brief, protected window that allows players to be present for the birth of a child without the club losing a roster spot entirely. The player is replaced temporarily, then reinstated. In the middle of a postseason series, the logistics compress considerably, but the mechanism worked as designed: Miller was gone for one game and back for the next.

Why it matters

The timing of Miller's return carries real operational weight. San Diego's bullpen entered Game 4 with at least one notable question mark: Adrian Morejon, one of the more closely watched left-handed relievers in the sport, had been unavailable for Game 3 due to a balky shoulder. Morejon remains on the postseason roster with no serious injury indicated, per prior Posterior Wire reporting, but his availability on any given night has been uncertain.

Into that context, Miller's return matters not just as a headcount but as a quality-of-arm question. A closer capable of handling the 7th inning gives a manager flexibility that a depleted or uncertain bullpen simply cannot offer. The fact that Miller threw a scoreless frame — not just appeared, but retired hitters — is the operative detail here.

It is also worth noting that Miller carried some recent history into Game 4. A few days before the series, he had attributed a blown save to a lack of command rather than any issue with tipping pitches — a distinction he made himself, and one the opposing manager also endorsed, per earlier reporting. Whether that command had fully returned was an open question heading into Game 4. One scoreless inning does not close every question, but it is a more useful data point than a bullpen session.

The numbers

San Diego's record stands at 91-71 (.562) on the season, good for 2nd in the NL West. The Padres have been eliminated from the division race, finishing 9 games back, but entered the postseason as the top Wild Card seed, sitting +3.0 relative to the cut line. They arrive at Game 4 riding a two-game winning streak.

Those 91 wins represent a club that earned its postseason standing through the full length of a season, not a late surge. The Wild Card position — rank 1, with a +3.0 cushion — reflects a team that was not scrambling to get in. That context matters when evaluating how the Padres are constructed: this is a roster built to go deep, not merely to qualify.

Where the club stands

San Diego sits 2nd in the NL West at 91-71, eliminated from the division title but holding the top Wild Card seed with a +3.0 margin over the cut line. The club enters Game 4 on a two-game winning streak.

The postseason roster has seen its share of movement even within this short series. Walker Buehler was activated off the paternity list ahead of Game 3 — yes, two Padres pitchers were on the paternity list in the same postseason series, which is either a remarkable coincidence or a very good offseason — and Ty France, who signed a minor league deal with San Diego in the 2025-26 offseason, has posted career-best offensive numbers in 2026, per prior reporting. The club that took the field for Game 4 is not identical to the one that opened the series, and the changes have not all been subtractions.

What we don't know yet

Morejon's shoulder remains the most significant open question in the San Diego bullpen. He is on the postseason roster and no serious injury has been indicated, but his game-to-game availability is not settled. Whether he pitches in Game 4 or beyond has not been reported.

Miller's workload management going forward is also unaddressed. He threw one inning in Game 4 after missing Game 3 entirely. How the club handles his usage in a potential Game 5 — or how deep into this series San Diego advances — has not been reported.

What to watch

The Morejon situation is the thread worth pulling. A healthy Miller-and-Morejon combination at the back of a postseason bullpen is a different proposition than one operating at partial capacity. If Morejon is available and effective in the remaining games of this series, the Padres' late-inning picture looks considerably more settled. If he remains limited, the club will be asking other arms to cover ground that was presumably allocated to him when the postseason roster was constructed.

Miller's command is also worth monitoring. His own assessment after the blown save — that it was a command issue — was candid and specific. One clean inning in Game 4 is a positive sign, but the sample is small and the stakes only increase from here. Whether that sharpness holds across multiple high-leverage appearances is the question the next few games will begin to answer.

The Padres, at 91-71 and riding a two-game winning streak, are in a position to advance. The bullpen, with Miller back and Morejon's status still uncertain, is the variable most worth watching as they try to do exactly that.
