Heads to 60-day IL
The Reds placed Williamson (elbow) on the 60-day injured list Wednesday.
ANALYSIS
Williamson is set to miss the entire 2025 season after undergoing Tommy John surgery last September, so his move to the 60-day IL is merely procedural. The transaction opens up a spot on the 40-man roster for catcher Austin Wynns, whose contract was selected from Triple-A Louisville.

Past Fantasy Outlooks
2024
2023
2022
Williamson looked worn out down the stretch in 2023, which was probably predictable given that it was his first big-league season. An early-September stint on the COVID IL may have also been a critical tipping point. Prior to the diagnosis, the 25-year-old left-hander held a 4.20 ERA and 87 strikeouts through 98.2 innings and was sitting 94-95 mph with his fastball. Following his return to the Reds' active roster, he gave up 12 earned runs and an .858 opponents' OPS across his final four starts covering 18.2 innings, with his fastball velocity dropping into the 91-92 mph range. Williamson will have to compete for an Opening Day rotation spot this spring and aim to rediscover the form that saw him register a 3.15 ERA and 58:16 K:BB in 60 innings (11 starts) between July and August last year. He should be on watch lists either way.

Latest Fantasy Rumors

Will be added to 40-man
Williamson will join Cincinnati's 40-man roster by Tuesday, reports Bobby Nightengale of The Cincinnati Enquirer.
ANALYSIS
Williamson spent time at both Double-A Chattanooga and Triple-A Louisville in 2022, posting a 4.11 ERA, 1.56 WHIP and 1.60 K/BB in 122.2 combined innings. It was a dramatic dip in production from his 2021 production when he was a member of the Mariners' organization. Moving him to the 40-man roster will protect him from being selected in December's Rule 5 Draft.
