                  Throwing program paused
Williamson (elbow) recently began throwing from a mound at the Reds' training facility in Goodyear (Ariz.) but has returned to Cincinnati, MLB.com reports.
                  Analysis
The report indicates Williamson was told to "throttle back," which suggests the stress of throwing from a mound was too much for the left-hander. He'll be with the Reds for the week to play catch and participate in workouts. Williamson is recovering from Tommy John surgery he underwent last September and is not expected back until 2026.

        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.
