The San Diego Padres possess the best bullpen in baseball. The eight arms that make up the Friars bullpen have a 3.03 ERA. The next best belongs to the San Francisco Giants with a 3.25 ERA. One of the biggest reasons for that success is the effectiveness of the high-leverage relievers known as the Four Horseman (thank manager Mike Shildt for that one).
Jeremiah Estrada (2.64 ERA), Adrian Morejon (1.66 ERA), Jason Adam (1.93 ERA) and closer Robert Suarez (3.50 ERA) combine for a 2.43 ERA. Their success in finishing games has been responsible for the Padres winning many of the games in which the starter was not able to go deep into a game.
