"It's exciting -- your adrenaline's definitely going, your blood's flowing pretty good," Quackenbush said. "It's a good time to be out there."
With Nick Vincent injured and Alex Torres likely unavailable after pitching in the Padres' last four games, Padres manager Bud Black had no hesitations calling on the rookie over established setup man Joaquin Benoit.
"I trusted him to get the lefty out," Black said. "Quack's been really good for us, and he delivered."
Since allowing a walk-off home run to A.J. Pollock in a loss to Arizona on May 26, Quackenbush has given up earned runs in just one of his 15 appearances, a span of 13 innings.
"I've just been trying to get [hitters] with strike one and see where the at-bat goes from there," Quackenbush said.
And after being shuttled between Triple-A El Paso and the Majors four times between April 25 and May 17, he seems to have finally carved out a permanent role in the Padres 'pen for 2014.
