I'm of a different mind. There's never enough bullpen. There never will be enough bullpen. There certainly isn't enough bullpen to help a team that scores zero runs. You stretch your bullpen not necessarily by thinking there's another guy just out of reach who can save you, but buy letting guys pitching well continue to pitch. A team used to be able to get a division title with seven or eight good pitchers, get through the playoffs with six or seven, and then only trust five guys in game situations in the World Series. The rest were just guys, taking up a roster spot, pitching low-risk situations, throwing strikes, and taking lumps. Now we have fallen into the notion that we think we need a dozen trustworthy guys. We don't, though. And there's nothing magic about 100 pitches. If we all had six fingers on each hand, we'd be letting starting pitchers throw 144 pitches, as long as they were effective, before pulling them. We'd need even smaller bullpens. Let guys who are effective keep pitching, score a few runs when you can, and run up the opposition pitch counts, and then you don't have to worry about getting more relievers. But there isn't enough pitching in the world to win your team is shut out. And there isn't enough room on the roster to keep enough pitching around to keep the game 0–0 forever.
