Nance was optioned to Triple-A Jacksonville on Thursday, Christina De Nicola of MLB.com reports.
The Marlins claimed Nance off waivers Sunday after he was designated for assignment by the Cubs. He made his major-league debut in 2021, and despite a disastrous 7.22 ERA showed some promising skills by racking up 30 strikeouts across 28.2 innings. Though he'll now begin the season at Triple-A Jacksonville, Nance will likely contribute out of Miami's bullpen at some point during the season.
