Byrnes also spent time doing a handful of interviews, with XM's MLB Radio Network and with XX 1090 in San Diego, the team's flagship station. He also spoke with MLB.com.
Byrnes, dismissed following 2 1/2 seasons, got back to friends in the industry who reached out Sunday when they first heard the news.
"The good side of yesterday was the appreciation you feel for your efforts from individuals in the game," Byrnes said.
That was Byrnes' biggest takeaway from Sunday's events, a change that he admitted he wasn't entirely surprised occurred even though he certainly didn't agree with it.
"So many great people and we had a really good process in many areas, the day to day, development, scouting, personnel choices," he said. "We wanted to progress and win and be in a race. But I think we all know this year the reasons that held us back. It's frustrating. But that's the nature of the game."
Entering Monday's game against the Giants, the Padres had scored the fewest runs in baseball (225) -- 43 fewer than the 29th-ranked team (Braves). They also ranked last in the big leagues in batting average (.214), on-base percentage (.274), and slugging (.339).
The Padres have also had injuries to several players they were expecting results from -- Chase Headley, Carlos Quentin, Cameron Maybin, Yonder Alonso and Jedd Gyorko. All have spent time on the disabled list.
Byrnes said he'll miss the dynamic of working with people in baseball operations, the daily interaction that went with the job, bouncing ideas off each other.
"It's been a great group of people to work with," Byrnes said. "I've been in enough organizations to know that these people know what they're doing and they're setting the bar high for the Padres."
