Rest-of-Season Projections
2025 Fantasy Outlook
Thompson dropped some weight last offseason, believing it would help better prepare him to compete for a spot in the Cardinals' rotation. A Sonny Gray injury allowed Thompson to break camp as part of the rotation, but the slimmed-down lefty struggled with his velocity and mechanics and was sent down to Triple-A Memphis by late April and remained there for the rest of the season. He was able to close out the year strong in September and, because he's out of minor-league options, Thompson should crack the Opening Day roster in 2025 either in the rotation or bullpen. However, he has a lot to prove before fantasy managers can trust him. Read Past Outlooks

Headed to IL
The Cardinals will place Thompson (lat) on the 15-day injured list Monday.
ANALYSIS
Thompson is dealing with a Grade 1 lat strain and is in the midst of a 3-to-4 week shutdown from throwing. He had been competing for a roster spot prior to suffering the injury, but it seems likely he'll be sent to Triple-A when he's healthy enough to take the mound again. Thompson had a rough go during five appearances in the majors last season, posting a 9.53 ERA, 1.88 WHIP and 20:8 K:BB over 17 innings.

Past Fantasy Outlooks
2024
2023
2021
In a season filled with minor controversies and culminating in a rare last-place finish for St. Louis, the Cardinals' mishandling of Thompson might have flown under the radar. He was told to prepare for a relief role at spring training before suddenly being optioned to Triple-A Memphis in early May to stretch out as a starter. He then returned to the majors to fill a bullpen opening in July before ultimately being pressed into starting duties by default following the deadline trades of Jordan Montgomery and Jack Flaherty. Thompson boasts an impressive fastball-curve-cutter arsenal and has been working to improve his changeup, but the 26-year-old southpaw could be faced with an even greater level of job uncertainty in 2024 after the Cards brought in veteran starters Sonny Gray, Kyle Gibson and Lance Lynn over the winter.

Latest Fantasy Rumors

In mix to start Saturday
Thompson is tentatively scheduled to start for Triple-A Memphis on Wednesday, but he remains an option to be called up to start Saturday for the Cardinals, per Jeff Jones of the Belleville News-Democrat.
ANALYSIS
The left-hander wouldn't make a start on two days' rest, but he shouldn't be considered unavailable until he actually takes the mound for Memphis. He began the season in St. Louis' rotation but shifted to the bullpen once Sonny Gray returned from the injured list, and Thompson was demoted to Triple-A in late April after he posted a 9.53 ERA and 1.88 WHIP in 17 innings. The 26-year-old has given up just three earned runs over 14.2 frames since he joined Memphis, though his 14:13 K:BB is worrisome.
