Maples was reassigned to minor-league camp Monday, Todd Zolecki of MLB.com reports.
Maples struggled as a non-roster invitee this spring, as he allowed five runs on three hits and three walks while striking out five in 2.2 innings. Although his strikeout rate remained high, he'll need to work on his command and ability to limit runs at Triple-A Lehigh Valley early in the 2022 campaign.
