A blown save is charged to any reliever who enters a save situation and lets the tying run score. Not just closers – anyone, any inning, and the lead doesn’t even have to be fully lost. The tying run crossing the plate is the whole trigger.
It’s the box score’s most public failure, home of baseball’s most backhanded stat line – the blown-save-and-win – and the number that ends more ninth-inning careers than any other. Here’s exactly how it works.
MLB EXPLAINED
The Blown Save
Any reliever, any inning, one tying run
THE TRIGGER
Lost the lead
Enter in a save situation, surrender the tie or lead
WHO CAN GET ONE
Any reliever
Not just closers – 7th-inning arms blow saves too
THE INSULT
The vulture win
Blow the save, get the win anyway
THE PAIR
SV% = SV/(SV+BS)
Conversion rate is the stat that matters
Blown saves, rule by rule
What officially counts as blowing it
| Rule |
Detail |
| The setup |
A reliever must enter in a SAVE SITUATION: lead of 3 or fewer runs, or the tying run on base, at bat or on deck – no save situation, no blown save possible |
| The blow |
He’s charged the moment the tying run scores – the lead doesn’t have to be fully lost, and the run counts whether it’s his runner or an inherited one |
| Any inning counts |
A setup man losing a lead in the 7th is charged identically to a closer in the 9th – blown saves are not a closers-only statistic, which surprises most box score readers |
| Inherited runners bite |
Enter with a man on third, allow a sac fly that ties it: blown save – even though the run belongs to the previous pitcher’s ERA. The BS and the ER can go to different people |
| The team can still win |
A blown save isn’t a loss – the offense can rescue the game, and often does |
| The vulture win |
Baseball’s backhanded reward: blow the save, watch your team retake the lead while you’re the pitcher of record, collect the W. A blown save AND a win in the same line |
Reading the stat like a front office
What blown saves actually reveal
| Angle |
Detail |
| Save percentage is the headline |
Raw blown save totals mislead – busy closers blow more saves because they get more chances. SV/(SV+BS) is the real skill number |
| Usage tells on managers |
A bullpen’s blown saves cluster where the manager puts his worst leverage decisions – the stat maps trust as much as talent |
| Not an official stat, universally kept |
Like the save itself, the blown save grew out of the save rule rather than the official rulebook’s original text – every stat service tracks it anyway |
| September amplifier |
A blown save in a pennant race carries playoff-odds weight that April’s version doesn’t – the stat is flat; the stakes aren’t |
BLOWN SAVE FACTS
The tying run is the line
Protect a 3-run lead but allow 2? No blown save. Allow the third? Charged – the boundary is the tie, not the damage.
Multiple per game is possible
A team can blow the same game twice – two relievers, two separate save situations, two entries in the box score.
Closers wear it publicly
No stat ends ninth-inning job tenures faster – a short stretch of blown saves reshuffles more bullpens than any front office memo.
The Fine Print That Surprises People
Two details trip up even seasoned box score readers. First, blown saves aren’t a ninth-inning stat – a setup man surrendering a 7th-inning lead is charged identically, which is why bullpen blown-save totals dwarf any one closer’s. Second, inherited runners count: a reliever can be charged a blown save on a run that goes to someone else’s ERA entirely. The stat’s cruelest cousin is the vulture win – blow the lead, stay in the game, watch your offense bail you out on the other side of a walk-off, and collect the W. Alongside the quality start on the front end, it’s half of how modern box scores grade run prevention by role. Definitions live in MLB’s official glossary.
The Bottom Line
Enter in a save situation, let the tying run score – that’s a blown save, charged to any reliever in any inning, inherited runners included. Judge closers by conversion rate, not the raw count – and savor the vulture win, baseball’s finest failure-into-reward pipeline.
