Marco Scutaro (back) will begin a rehab assignment with the rookie-level Arizona League Giants on Tuesday. Scutaro will play three innings in what will be his first game action since spring training. The second baseman underwent a blood-spinning procedure in mid-May for his chronic back issue and appears to finally have made a bit of progress. While it's nice that Scutaro is playing in games again, it remains totally up in the air as to when he might return to the Giants.
