Diaz reported to the Mets' big-league camp Tuesday after resolving his visa issues, Anthony DiComo of MLB.com reports.
Diaz will be behind the Mets' other pitchers after missing more than a week of workouts, but as a reliever, he's unlikely to need much buildup time. He covered 25 innings out of New York's bullpen in 2021, accruing a 5.40 ERA and 1.48 WHIP.
