Asked if he feels freer to throw with abandon as a reliever as opposed to conserving his energy as a starter, Vogelsong said Wednesday, "With the fastball, yeah." But he added that his sharper stuff also can be attributed to intangibles.
"It's just like a hitter," said Vogelsong, who has allowed one earned run in 7 2/3 innings spanning his last five relief appearances. "You feel comfortable or you get in one of those stretches where you don't feel comfortable. This is one of those stretches right now where everything's feeling pretty good. I feel fresh; I'm sure that probably helps."
Vogelsong's currently one of eight relievers on the Giants' staff. With the starters struggling to last as long as six innings per outing, manager Bruce Bochy needs as much reinforcement as he can receive from the bullpen, which entered Wednesday with a 0.74 ERA since the All-Star break.
