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
Getting back on track
Kerkering (4-1) was credited with the win in Saturday's 9-6 extra-innings victory over the Athletics, allowing one hit and two walks with no strikeouts during a scoreless 10th inning.
ANALYSIS
Both of Kerkering's walks were intentional, and he's now worked seven consecutive scoreless outings. The 24-year-old right-hander has improved his ERA from 6.48 on April 22 to 3.72 by giving up just two runs over his last 11 frames. Jordan Romano is positioned as Philadelphia's closer, but Kerkering remains in the high-leverage mix as a setup man with eight holds in 2025.

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.
