PHOENIX -- The Diamondbacks placed reserve infielder John McDonald on the 15-day disabled list Monday with a strained left oblique and activated fellow bench infielder Geoff Blum for the 60-day DL. Blum had been sidelined since April 18 with the same injury.
"We're being conservative about (McDonald)," D-backs manager Kirk Gibson said. "Realistically it could be as quick as a week."
McDonald's DL stint is retroactive to June 25 because he has not played since June 24. He was in the lineup Saturday at Milwaukee but was scratched after telling Gibson he couldn't play. McDonald could be activated as soon as the Diamondbacks' first game after the All-Star Break, on July 13 in Chicago.
Blum, 39, finished a 12-game rehab assignment with Triple-A Reno on Saturday. He hit .237 (9-for-38) with three doubles, a home run and eight RBI. He previously appeared in 11 games for the D-backs this season.
