The infielder began the season in the D-backs organization and played in 17 games in the big leagues before being designated for assignment on May 21.
He signed with the Brewers and played in 64 games for them before being placed on waivers last week. And with shortstop Willie Bloomquist battling back stiffness, the D-backs decided to claim him to provide some infield insurance.
"It's good to be back," Ransom said. "I enjoyed my time here. Really nice to be home. It's nice to be coming to a team that's in the hunt still."
This is not the first time in his career that Ransom has started a season with an organization, left it and then returned. It happened to him in 2005, when he started with the Cubs' Triple-A team, went to the Rangers' Triple-A team and then wound up back with the Cubs.
It's a lot of upheaval for him, but Ransom is thankful to be back with the D-backs, especially since he lives in the Phoenix area and has kids getting ready to go back to school.
"It's the way the game works," he said. "You don't always love it, you don't know always why things happen, but they happen for a reason. The more open you are to accepting that the easier it makes it. I'm still playing baseball and it's a game. We're pretty lucky to be in the situation we're in. I loved it when I was here and I'm real happy to be back."
