The Cardinals are expected to promote Bernal from Triple-A Memphis on Tuesday, Francys Romero of BeisbolFR.com reports.
Bernal will make the jump to the major-league level after slashing .278/.363/.468 with 16 home runs and nine stolen bases over 101 contests with Memphis this season. The 22-year-old has played primarily behind the plate, but he has also seen some exposure to first base and designated hitter during his time at Triple-A.
