2023 Fantasy Outlook
Puk finally faded the injury bug, setting personal marks in both innings (66.1) and games played (62) after moving to the bullpen. The 6-foot-7 southpaw struck out 76 batters via his 97 mph fastball, slider and occasional sinker, while maintaining mostly above-average Statcast metrics. The few areas of deficiency were barrel percentage (8.8%) and walk rate (8.2%), especially after Puk exhibited shaky control in the second half. However, Puk's ascension to high leverage was no surprise, especially given the wave of injuries to his bullpen mates. He compiled four wins, 20 holds (T-13th in AL) and four saves, three of which came within a two-week span right after the All-Star break. Puk has the upside to close full-time, but he'll open spring training in the competition for a rotation spot. He's primarily worked as a reliever since he underwent Tommy John surgery in 2017, so his outlook is murky at best if he sticks as a starter. Read Past Outlooks

Earns playoff-clinching win
Puk (7-5) earned the win Saturday against the Pirates, allowing one run on three hits over two innings while striking out three. He did not issue any walks.
ANALYSIS
Puk entered the game in the bottom of the fourth and struck out two of the first four batters he faced to get through the inning. However, the lefty reliever got himself into trouble in the fifth after surrendering a leadoff double to Ke'Bryan Hayes to open the frame, which would lead to one run coming across for the Pirates. Fortunately for Puk, the Marlins' offense would come through with two runs in the bottom of the inning, helping him secure his seventh win of the season as Miami clinched only its fourth playoff berth in franchise history.

Health issues and ineffectiveness have limited Puk to 24.2 big-league innings since he was drafted as the sixth overall pick in 2016. The southpaw didn't break camp with Oakland last season, but was promoted in April and made one appearance in long relief before suffering a strained left biceps that forced a trip to the injured list. He was not activated until late-May and was optioned to Triple-A after getting hit hard during his rehab. Puk has yet to start a game in the majors with just 22 relief appearances on his resume, so it's fair to start questioning whether a starting role is still in his future. Last year, he went three innings or more just four times in 41 appearances between the majors and minors. He also lost a few ticks on his fastball and slider compared to 2019 and both pitches were far less effective. However, Puk still has plenty of upside and is worth a late-round flier in deeper leagues.
