  We use the NIRSPEC near-IR spectrometer on Keck II to obtain moderate
resolution (R = 1540) spectroscopy that shows conclusively that the C IV
emission line in the z = 5.74 quasar SDSSp J104433.04-012502.2 is accompanied
by broad, blueshifted C IV absorption. The line has a "balnicity index" of 900
km/s and a rest-frame equivalent width of 13.1 +/- 1.3 relative to the
continuum. This confirms its membership in the class of objects called
"broad-absorption line" (BAL) QSOs. SDSSP J1044-0125 was previously suggested
to be a BAL QSO based on its larger UV-to-X-ray flux ratio than most non-BAL
QSOs. The C IV emission is of normal strength, implying a metallicity similar
to that found in other, lower-redshift QSOs.
