Scutaro has been sidelined for most of the spring with back problems.
The Giants didn't make an official announcement before their game against Colorado on Wednesday. But the 38-year-old Scutaro says he is likely to remain in Arizona for more treatment when the team breaks camp.
Scutaro was plagued by back stiffness for most of the 2013 season. He had a couple of epidural injections earlier this spring and recently had a cortisone injection.
Scutaro's situation likely will leave Joaquin Arias as the starting second baseman. Arias started at third base on Wednesday, with Pablo Sandoval nursing a small cut in his hand.
