With such a stellar pitching staff that consistently goes deep into games, having seven relievers is superfluous. Especially when you consider that the best one, Sergio Romo, has only pitched 15.1 innings all year, just over half of Guillermo Mota's total.
Of the five relievers on the roster not named Brian Wilson or recently-activated Santiago Casilla, four have an ERA under 3.16 and a WHIP under 1.30.
The odd man out? Jeremy Affeldt, with a 5.82 ERA and 1.71 WHIP.
The Giants need offense more than pitching right now, and could use the extra bench spot for a pinch hitter or pinch runner.
This move would be impractical right now, as the beleaguered Giants might not have any one to call up.
But when Pablo Sandoval, Darren Ford and Mike Fontenot all return from injury, San Francisco will have some personnel decisions to make. They could opt to keep one of Belt, Burriss or Crawford on the roster if they go with a six-man bullpen.
