Around 9 a.m. on Monday, a group of Salt River Fields employees leaned over a railing near the Diamondbacks’ complex and called toward a tall, lanky man down below.

When he looked up and waved, everyone seemed content. Randy Johnson was in camp.

The man most likely to be the Diamondbacks’ first representative in the Hall of Fame has had a frosty relationship with his old organization in recent years. But there he was, watching Diamondbacks pitchers throw in bullpen sessions early Monday morning, after which he stood and talked with veteran Trevor Cahill and prospect Chase Anderson for more than 10 minutes.

He also visited with familiar faces, joking that some his former teammates have become coaches.

“I’d like to think I have a little bit of wisdom from my times of playing,” Johnson said. “It’s nice to be able to come out here. … I knew there would be a time and a place when I would finally get back into the baseball mode or at least come and watch something like this.”

Johnson doesn’t have a role or a title, but the Diamondbacks made it clear they are glad to have him back in the organization whenever he’s comfortable.

Johnson said he might be back in camp again before the end of the week.

“We’d love him to be an asset if he wants to do that,” Diamondbacks manager Kirk Gibson said. “He knows he’s welcome.”

Johnson has remained busy since retiring after the 2009 season, spending time with family, traveling and focusing on photography, a longtime hobby. He also spoke passionately about his experiences on USO tours. But he said getting away from baseball has only drawn him back.

“For me, it was a matter of detoxing and kind of detaching a little bit,” he said. “I anticipate being around a little bit more over time.”
