Giants' Sanchez out with twisted knee
Sanchez was helped off the field immediately after Mark Reynolds of the Diamondbacks hit a two-run home run with two outs in the bottom of the inning. Sanchez may have been hurt on the previous play when Justin Upton flied out to center field.
Kevin Frandsen replaced Sanchez, who was acquired by the Giants in a trade with Pittsburgh on July 30. There was no word on how long Sanchez could be sidelined.
