• Craig Tatum, a 29-year-old non-roster invitee catcher, told the team he was retiring. The timing of the news stunned the Marlins.
Tatum has played in 100 big league games, but none since 2011. Miami now has six catchers in camp, and 73 players overall.
• All is well on the injury front for the Marlins. None of the pitchers are being held back.
• Wednesday's workouts begin around 10 a.m. at the Roger Dean Stadium complex. Full-squad workouts get under way on Friday.
