2024 Fantasy Outlook
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. Read Past Outlooks
Shifts to 60-day injured list
The Reds transferred Williamson (elbow) to the 60-day injured list Tuesday.
ANALYSIS
The transaction clears a spot on the 40-man roster for Ian Gibaut, who was activated from the 60-day IL. Williamson is set to undergo Tommy John surgery, which is likely to sideline him until 2026.

Past Fantasy Outlooks
2023
2022
Williamson was one of the key pieces acquired by the Reds from the Mariners in the Jesse Winker/Eugenio Suarez trade. The former second-round pick was coming off a dominant 2021 season in the minors which concluded at the Double-A level, setting himself up to be part of the Reds' 2022 rotation at some point. It didn't happen, though, as the left-hander showed regression across the board both in terms of numbers and stuff. His lack of control was particularly alarming, as he went from an 8.1 percent walk rate in 2021 to a 13.9 percent walk rate in 2022. Williamson was added to the 40-man roster over the offseason, and there should be starts available to him for the Reds if he can bounce back. Fantasy managers should take more of a wait-and-see approach, though.

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.
