Drew leaves game with midsection tightness

SCOTTSDALE, Ariz. -- D-backs shortstop Stephen Drew was removed after the first inning Wednesday due to "midsection tightness."

"Just a little discomfort in the abs section, the midsection," Drew said. "It's kind of bothered me today, so [it is] just kind of precautionary. I came out to get it checked out. Everything seems to be OK, so it's just day by day."

Drew said he believes he suffered the injury during Tuesday night's game, because he woke up Wednesday feeling a little discomfort.

"I thought it would go away by the time I got loose," Drew said. "It's just kind of nagging me."

Drew was not scheduled to play Thursday against the Dodgers even before the injury, but said he was "hopeful" about playing Friday.

Blum day-to-day with right knee injury

SCOTTSDALE, Ariz. -- Infielder Geoff Blum will miss the next couple of days with swelling in his right knee.

"I just strained it a couple of days ago and it swelled up a little bit," Blum said. "So we're going to wait for the swelling to go down a little bit, limit the activity for the next few days and then get after it again."

D-backs manager Kirk Gibson said the club wanted to be cautious in how it dealt with Blum, who signed a two-year contract during the offseason.

"I think [Thursday] he may do some hitting," Gibson said. "You don't want it to flare up anymore. He's not a young guy. We'll be cautious with that. We don't want it to get crazy on him."

Blum, 37, said he did not remember a particular play that caused the injury.

"I think it was just wear and tear, just over abuse at my young age," Blum said. "I'll be alright, no panic."
