  Using proper motions from Gaia Early Data Release 3 (Gaia EDR 3) and radial
velocities from several surveys, we identify 60 candidate high-velocity stars
with total velocity greater than 75\% escape velocity that probably origin from
Sagittarius dwarf spheroidal galaxy (Sgr) by orbital analysis. Sgr's gravity
has little effect on the results and the Large Magellanic Cloud's gravity has
non-negligible effect on only a few stars. The closest approach of these stars
to the Sgr occurs when the Sgr passed its pericenter ($\sim$ 38.2 Myr ago),
which suggest they were tidally stripped from the Sgr. The positions of these
stars in the HR diagram and the chemical properties of 19 of them with
available [Fe/H] are similar with the Sgr stream member stars. This is
consistent with the assumption of their accretion origin. Two of the 60 are
hypervelocity stars, which may also be produced by Hills mechanism.
