Hendry and Sandberg most likely will continue their conversation on Wednesday, according to the same source.
Hendry had some conversations with Sandberg at the end of August when he visited the Iowa Cubs on the road in Albuquerque, N.M.

According to sources, Hendry is still planning conversations with Washington coach Pat Listach, former Arizona manager Bob Melvin and Cubs broadcaster Bob Brenly. The only confirmed expanded interview that Hendry has completed so far is with former Cleveland manager Eric Wedge.
Sandberg was the manager of the year in the Pacific Coast League in 2010. He's managed in the Cubs organization the past four seasons.
Former double-play partner Shawon Dunston, in town as part of the Giants' coaching staff, was a little surprised by Sandberg's post-playing coaching experience.
"When we sat around when we were young, we all knew Joe Girardi would be a manager, we knew Ryno would be a Hall of Famer and we knew Andre [Dawson] and Greg [Maddux] would be Hall of Famers. But no, I never envisioned Ryno being a manager."
Dunston, who played next to Sandberg for portions of 10 years, hasn't been in touch with him since spring training.
"I hear he gets thrown out of games," Dunston said. "He never got thrown out when I played with him. That's kind of funny, right there, because he'd only say three or four words a day when we played together."
