Since the 2010 trade deadline, when the San Francisco Giants acquired Lopez from the Pittsburgh Pirates, these four pitchers have been literal Giants. They have been the core of a bullpen that consistently stopped some of the best lineups in baseball. Affeldt’s scoreless inning streak of 23 innings was recently passed by starter Madison Bumgarner. Only future Hall of Fame closer Mariano Rivera has a longer streak than Bumgarner.
Romo, Casilla and Lopez all had scoreless inning streaks heading into the 2016 post-season as well. When it came to Bruce Bochy‘s bullpen, it seemed he could always count on these four men in October.
