The Cardinals optioned Donovan to Triple-A Memphis on Sunday, Derrick Goold of the St. Louis Post-Dispatch reports.
The 25-year-old submitted a .689 OPS over 32 at-bats during spring training and drew praise from manager Oliver Marmol for his versatility and plate approach, so it wouldn't be surprising if Donovan gets a look with the big club early on during the 2022 season. At least for the start of the campaign, however, he'll head to Memphis to play on an everyday basis.
