2024 Fantasy Outlook
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.

July 1, 2024
Triple-A Memphis placed Thompson on its 7-day injured list Monday with an unspecified injury.
ANALYSIS
Since the Cardinals sent him back to Triple-A in late April, Thompson has filled a spot in the Memphis rotation, compiling a 4.17 ERA, 1.50 WHIP and 54:35 K:BB in 45.1 innings. Though finding strike zone has been a consistent problem for Thompson throughout his professional career, an injury could be at the root of why he was more wild than usual in his most recent Triple-A start Friday, when he walked six batters over three innings. Thompson is without a clear timeline for a return from the IL.

Past Fantasy Outlooks
2023
2021
The Cardinals drafted Thompson with the 19th overall pick in 2019. Called up in early June of last year, Thompson made a splash right away, becoming the first player in 45 years to pitch four or more innings and record the save in their big-league debut. A starter at Triple-A in 2021, Thompson began his transition to the bullpen over the first couple months of last season and ended up pitching almost exclusively in relief as a rookie (22 appearances, one start). He was fantastic from a run-prevention standpoint, though the underlying numbers were less impressive, in particular a strikeout rate a shade under 20 percent. A lot will be asked of his defense once again in 2023. Expect some giveback and don't bother in a mixed league unless Thompson is getting starts for St. Louis.
Thompson has had quite the baseball journey. He should have been a high draft pick coming out of high school, but concerns about his shoulder and desire for college dropped him to the 11th round. He failed his post-draft physical, went to college and had more medical problems around some quality pitching. He was drafted in the first round of the 2019 draft and casually used out of the bullpen in the lower levels of the minors. His best pitch is a nasty curveball and he also nice slider to go along with his fastball and changeup. If the injury issues are behind him, he is an intriguing draft-and-follow in keeper leagues. It is unlikely he does anything more than September pitching, but a stash for long-term leagues is worthy of consideration here.

Latest Fantasy Rumors
In mix to start Saturday
PSt. Louis Cardinals  AAA
May 21, 2024
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.
