Rest-of-Season Projections
Plans changing
Williamson will start the fifth game of the regular season, March 31, against Pittsburgh, Rich Rovito of MLB.com reports.
Analysis
Williamson was planned to be part of a three-pitcher grouping that would occupy the fourth and fifth rotation spots, but that plan changed. The Reds need to adjust to being without Nick Lodolo (blister), who will open the regular season on in the injured list. That paves the way for Williamson, Chase Burns and Rhett Lowder to each have their own spot in the rotation to begin the season.

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.
