Blum was signed to a two-year contract prior to the 2011 season and was expected to see significant time at third base.
However, a right knee injury forced him to miss the first 92 games of the season, and once he returned it was only a matter of days before he fractured his right pinkie and had to miss another 35 days.
"You're trying to make an impression on your new team and you blow out," Blum said of how spring went last year for him. "Not good."
Blum said he shed about 10 pounds during the offseason in order to reduce the stress on his knee, changing up his usual offseason routine as well.
"I couldn't do a lot of the weight bearing things and stuff like that," Blum said.
The D-backs will take things slowly with Blum this spring to try and avoid a repeat of last year.
"He looks like he's in great shape," D-backs manager Kirk Gibson said. "He had a tough spring last year, so we're going to try and avoid that. Blummer will be a guy we want to be smart with. We don't want to have him come out here and overdo it, and then we're back where we were last year."
