Mason Miller's stats since 2nd Padres appearance is best relief stretch in MLB history

Since a rocky second appearance with the Padres last August, Mason Miller has authored the kind of relief stretch that barely looks believable. What makes it even more jarring is where it began. On August 5, 2025, Miller gave up a game-tying two-run homer to Lourdes Gurriel Jr. on a 103.9 mph fastball in just his second outing with San Diego, turning a blown save into a bit of unwanted history.

That pitch became the fastest homer hit in the pitch-tracking era, which made the moment feel even louder at the time. But instead of serving as some warning sign, it has become the clear dividing line in Miller’s Padres tenure. Since that night, he has been almost untouchable, turning one ugly early moment into the starting point of a stretch that now belongs in any serious conversation about the most dominant relief runs the sport has seen.

Padres’ devastating Mason Miller stretch is starting to feel completely historic

Miller has not allowed a run since that August 5 outing, and his scoreless streak has reached 25 2/3 innings, the longest active scoreless streak in the majors. Over that run, opposing hitters have managed just five hits, all singles, while Miller has posted absurd leaderboard numbers in opponent batting average, slugging percentage, strikeout rate, and whiff rate. 

So when people bring up the idea of the Padres eventually stretching him back out as a starter, this is the answer. This is why those talks never really gained serious traction. You don’t take a weapon like this and voluntarily make it less terrifying.

Starting is valuable. The Padres of all teams know this. But so is having a late-inning monster who can make the final three outs feel unfair.

What stands out even more is that the scoreless-inning streak alone does not fully capture how overpowering Miller has been. During this run, nearly sixty percent of the hitters he has faced have struck out.

And Padres fans know what elite bullpen theater looks like. This franchise has had some real late-inning sickos over the years. But Miller is already forcing his way into that conversation almost immediately, which is ridiculous when you think about how short his San Diego tenure still is. His 0.65 ERA through his first 26 appearances with the Padres is the third-lowest mark by a pitcher through that many outings in franchise history. 

That is the part that should jump out most. He is not just piling up saves or piling up strikeouts. He is dropping himself into Padres closer lore at warp speed.

This is the kind of stretch people bring up years later when they are trying to explain how unhittable a guy looked in real time.

And for the Padres, that means the closer conversation is over.
