"I wasn't as nervous as I thought I would be," Scribner said. "I think I was more nervous going into the dugout after my first inning before going back out there."
Scribner made his debut in Tuesday's 8-2 loss to the Braves, tossing two scoreless innings with one walk and two hits allowed.
"I felt good about it. I was throwing strikes. I was trying to stay calm," said Scribner, who was recalled from Triple-A Tucson on Monday. "I wish I could have had a strikeout, but I guess you can't have everything."
Scribner threw 24 pitches (17 for strikes) and said Wednesday that he was ready to get back out there. As the closer this season for Tucson, Scribner is accustomed to pitching on consecutive days.
San Diego manager Bud Black was impressed with Scribner's fastball and curveball as well as the speed differential he showed between the two pitches.
"At times we saw a 20 mph difference with the same arm speed," Black said. "It's always nice to get the first one out of the way with a good performance."
Scribner, who is from Connecticut, had a phone brimming with congratulatory messages when he checked it after his debut.
"I came back in after the game and had 30 or so texts and a couple of phone calls. That was awesome," Scribner said.
