The San Francisco Giants’ bullpen has a real argument as the single best unit in all of baseball. It’s deep, with a blend of young ascending players and experienced veterans that gives manager Bob Melvin the ability to get strikeouts, force soft contact, or anything in between. Ryan Walker entered the season as one of the faces to the Giants’ bullpen before anyone know how consistently dominant of a unit it would be. Walker, 29, has a 4.64 ERA and a 1.15 WHIP in 2025.
