The Arizona Diamondbacks have placed infielder John McDonald on the 15-day disabled list with a strained left oblique.
Team reinstates Geoff Blum @Blummer27 from 60-day DL and places John McDonald on 15-day DL— Arizona Diamondbacks (@Dbacks) July 2, 2012
In a corresponding roster move, the Diamondbacks activated infielder Geoff Blum from the 60-day DL.
McDonald’s move to the DL is retroactive to June 25. The 37-year-old has hit a respectable .267/.308/.488 with 11 extra-base hits and 12 RBIs over his 86 at-bats this season. McDonald has primarily played shortstop for Arizona, though the veteran has also manned third and second base.
It’s unclear how long McDonald will be sidelined, though oblique injuries generally take at least a month to recover from.
Blum hasn’t appeared in a game for the Diamondbacks since April 16. As is currently the case with McDonald, Blum was dealing with an oblique injury that ultimately sidelined him for roughly two and a half months.
Blum went 1-11 over his eight games with the Diamondbacks before hitting the DL in April. The 39-year-old is a career .250/.311/.385 hitter.
