2025 Fantasy Outlook
Kerkering's first full season in the majors was delayed by a few weeks due to what the Phillies called a "right forearm strain". In reality, the 23-year-old was simply rebuilding strength after missing extensive time during spring training due to a severe case of the flu. Kerkering was activated in mid-April and pitched on the lower-end of Philadelphia's high-leverage hierarchy, typically working the sixth or seventh innings. The rookie was outstanding, posting a 2.29 ERA (3.19 xERA) and 1.08 WHIP over 63 innings with a 23.2 K-BB percentage that ranked 20th among qualified relievers. Kerkering failed to record any saves in 2024, but remains in the conversation as a potential closer of the future in Philadelphia. Read Past Outlooks
Blows save, earns win
Kerkering (3-1) allowed four runs (one earned) on three hits over one inning against the Phillies on Tuesday. He struck out two and earned a win after being charged with a blown save.
ANALYSIS
Kerkering gave up an RBI double to James Wood and a three-run shot to Nathaniel Lowe after entering with a 5-2 lead. Fortunately for Kerkering, an error in the frame kept three of those runs from affecting his ERA. He gave up one run through his first seven innings of the season but has since allowed nine runs (six earned) over his last 4.1 frames, spiking his ERA to 5.56. Jose Alvarado allowed two hits and struck out three in a scoreless eighth inning.

2024 Fantasy Outlook
A fifth-round pick of the Phillies in 2022, Kerkering opened last season in the minors with the team's Single-A affiliate. He ended 2023 pitching high-leverage innings for Philadelphia in the NLCS, as the 22-year-old right-hander was simply too dominant for the minors. Kerkering posted a remarkable 1.51 ERA, 0.89 WHIP and 79:12 K:BB ratio over 53.2 innings while advancing through four levels. The South Florida alum boasts one of the most unique pitches in the game - an 86 mph sweeping slider with 18.6 inches of horizontal break that he threw 85% of the time. The average velocity of a sweeper or slider with 17-plus inches of horizontal break is a mere 80.6 mph, putting Kerkering's pitch on another level. Not to mention, his sinker approached triple digits, topping out at 98.8 mph during the playoffs. It's clear Kerkering has the stuff of a future closer, possibly as early as 2024, but his control is likely to impact whether or not that occurs this season.

Latest Fantasy Rumors
Benefiting from rehab assignment
Kerkering noted Friday that he's been getting a better feel for his two-seam fastball during his rehab assignment, Alex Coffey of The Philadelphia Inquirer reports.
ANALYSIS
Kerkering said that his time in the minors and "seeing different hitters and seeing what they do" has helped him figure out how to better use his two-seamer. He started the season on the 15-day injured list due to a right forearm strain and a bad case of the flu that kept him from pitching in Grapefruit League games after March 1. In his latest outing with Single-A Fort Myers, Kerkering pitched a scoreless inning with three strikeouts, and he is expected to return to the Phillies' bullpen this weekend. The 23-year-old has the makings of a future closer.
