We report the spectral lag analysis for GRB 180727A
(Beardmore et al., GCN Circ. 23043; Lien et al., GCN Circ. 23047)
based on the BAT data. The lag analysis finds a lag of 80 +- 27 ms
for the 50-100 keV to 15-25 keV band. Despite the short T90 duration
(1.1 +- 0.2 s), the lag value is consistent with that of long GRBs.
