The Twins reassigned Smeltzer to minor-league camp Sunday, Do-Hyoung Park of MLB.com reports.
Smeltzer's long-shot bid for the Twins' Opening Day roster likely ended when Minnesota signed Chris Archer last week to fill the fifth and final spot in its rotation. The 26-year-old lefty is expected to head to Triple-A St. Paul to begin the upcoming campaign and will remain on hand as organizational starting depth for Minnesota.
