SAN FRANCISCO (AP) -- Giants outfielder Nate Schierholtz tested his broken right foot and is still too sore to play.
He went without a walking boot Friday for the first time this week and did some early sprint work.
Schierholtz fouled a pitch from Atlanta's Tim Hudson off his foot in the series opener with the Braves on Aug. 15. Schierholtz played through it, then had an MRI during Monday's off day. A CT scan followed to confirm the fracture.
Injured closer Brian Wilson, nursing elbow inflammation, threw for six minutes on flat ground for the second straight day. Fellow reliever Sergio Romo, who also has an inflamed pitching elbow, threw one inning Friday in Arizona rookie ball and could be activated Sunday.
The Giants are calling up Eric Surkamp from Double-A Richmond to pitch Saturday in his major league debut.
