No, it wouldn't. History has shown us that the best high-leverage relievers usually end up with roughly the same value contributed as the best starters. That's both wildly wrong and missing the point. I don't have a four-run example easily available, but there was a perfect three-run example last night. Let's say a pitcher comes in to start the top of an inning with a tie game and allows three runs. If that inning was the first, that pitcher has taken his team from a 50% chance to win the game to a 19.8% chance to win the game, using historical results. He's cost his team .302 of a win. If that inning was the ninth, that pitcher has taken his team from a 50% chance to win to a 1.9% chance to win, costing his team .481 of a win. His team has 1/6th the chance of winning that it did before. If we talk about the difference between a shutout inning and giving up a single run, the difference is even more dramatic. A pitcher comes into the top of the inning with the game tied. If he pitches a shutout inning, then his team now has a 55% chance to win the game if that inning was the first, and a 64.6% chance if that inning was the 9th. If he allows exactly one run, that team now has a 42.5% chance of winning if it was the first, and a 12.1% chance to win if it was the ninth. Top of first, tied: Zero runs = 55% chance of winning, one run = 42.5% chance of winning. Top of ninth, tied: Zero runs = 64.6% chance of winning, one run = 12.1% chance of winning. Clearly, the ninth is wildly more important. All innings are not created equal. Starters do pitch, on average, in more close situations than relievers. That does not refute that Carlos Marmol's innings are just as important as a starter's in sum for two reasons. One, close is only half the equation of importance. Lateness is the other. And second, Marmol doesn't have the usage pattern of an average reliever. He has the usage pattern of a reliever targeted for use in close games.
