With runners on first and second and one out in the seventh inning and the D-backs trailing, 4-3, manager Kirk Gibson brought in Ziegler to face Michael McKenry, and the result was an inning-ending double play.
"He's been doing it a ton," Gibson said. "We kind of save him down there for when we get in trouble."
Ziegler, who throws sidearm, does not have overpowering stuff, so he focuses on throwing strikes and keeping the ball down.
"Ideally, I want to attack those guys, and I'm trying to get bad contact," Ziegler said. "I pitch to contact most of the time. If I get a chance to strike a guy out, I'll go for it, but I hardly ever start an at-bat thinking, 'I want to strike this guy out.' I'm hoping they hit it on the ground, and hopefully at that point it's at somebody.
"I can't control whether it goes through the hole, but I can hopefully have an idea, or at least attempt to control, how hard they hit it, so even if it is in a hole, maybe we can get over and at least knock it down and keep them to a single and then get a double play with the next guy."
Ziegler, who spent his entire career in the American League before coming to the D-backs just before the non-waiver Trade Deadline in 2011, says that his goal is to throw a maximum of 10 or 12 pitches per inning.
"A lot of guys will take pitches on me just because they haven't seen me before," he said. "In a lot of ways, I'm still new to the National League, so I'm facing some guys for the first time. Those guys, I really have to attack them, otherwise I can get myself behind in the count real quick."
