Puk was traded from the Athletics to the Marlins in exchange for JJ Bleday on Saturday, Ken Rosenthal of The Athletic reports.
Puk was expected to compete for a rotation spot with the Athletics this spring, but now will head to the Marlins, and will likely be a member of the Miami bullpen. The left-hander is not long removed from being considered among the top left-handed pitching prospects in baseball, but he has battled injuries and worked exclusively in relief since he underwent Tommy John surgery in 2017. He was effective in that role in 2022 with a 3.12 ERA and 76:23 K:BB over 66.1 innings for the A's. Puk could battle for a high-leverage role for the Marlins in 2023.
