Trevor Hoffman is second in major-league history with 601 saves. Saves tend to be viewed with disdain among more sabermetic fans as are relief pitchers in general. And, in fact, on a straight value measure, using Player won-lost records, Mariano Rivera is probably the only relief pitcher that I would be inclined to vote into my personal Hall of Fame.

That said, I think that Trevor Hoffman is underrated by many sabermetric fans. For example, I have read a number of online fans who have argued that Billy Wagner was better than Trevor Hoffman. And it's not terribly difficult to understand why. For his career, Hoffman had a 2.87 ERA which Baseball-Reference translates into an ERA+ of 141, while Wagner had a career ERA of 2.31 (ERA+ of 187). Hoffman did pitch 186 more innings than Wagner (1089.1 to 903), but that's a big gap in ERA/ERA+.

ERA matters, but, for relief pitchers, perhaps not as much as you might think. First, there are inherited runners, whose runs are not charged to a relief pitcher but, depending on exactly what base they started on and how they scored, could be at least partly the fault of the reliever. Trevor Hoffman was exceptionally good at stranding inherited runners. For his career, he entered games with 346 runners on base, 70 of whom scored (20%). For his career, Billy Wagner allowed 28% of inherited runners to score (46 of 166).

But perhaps more importantly, while saves are, perhaps, somewhat overvalued, and the rigidity of the closer role based entirely on the save rule is silly and occasionally infuriating, the job of a closer entering a save situation is not really to minimize the number of runs allowed, it's to save the game. Now, the easiest way to do that, of course, is to retire as many batters as possible as quickly as possible. But, at the end of the day, the success of a closer is in the number of wins he closes out.

For his career, Trevor Hoffman had 601 saves, 18 holds, and 76 blown "saves" (blown saves mix situations that, if successful, could have been either holds or saves), a success rate (saves + holds divided by total chances) of 89.1%. Billy Wagner had 422 saves, 13 holds, and 69 blown saves, a success rate of only 86.3%.

And what about the man who broke Trevor Hoffman's career save record? In his career, Mariano Rivera allowed 29% of inherited runners to score (107 of 367) and had 652 saves, 28 holds, and 80 blown saves, a success rate of 89.5%, better than Hoffman's 89.1%, but not by all that much.

Player won-lost records are, of course, designed to measure precisely how a player contributes to his team's victories. For example, the split in blame for inherited runs scoring is calculated precisely based on the exact situation in which the runners are inherited.

When the subject is relief pitchers, it's hard to beat Mariano Rivera. But Trevor Hoffman has a very good case for being the second-best relief pitcher in major-league history.

Hence, any numbers cited within these articles should automatically incorporate the most recent update to Player won-lost records. In some cases, however, the accompanying text may have been written based on previous versions of Player won-lost records. I apologize if this results in non-sensical text in any cases.
