Diamondbacks' Christian Walker: Activation imminent

Walker (oblique) will rejoin the Diamondbacks for this week's series in San Francisco, Jesse Friedman of GoPHNX.com reports.

It would appear he will be activated from the 10-day injured list during the series, perhaps as soon as Tuesday. Walker has been working out at the team's spring training complex in Arizona and got in some live at-bats over the weekend. The first baseman has been sidelined since late July with a left oblique strain.
