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.

Set to lose rotation spot
PSt. Louis Cardinals
April 7, 2024
Thompson is expected to lose his rotation spot and move to the bullpen with Sonny Gray (hamstring) on track to return from the 15-day injured list to start Tuesday's game against the Phillies, Jeff Jones of the Belleville News-Democrat reports.
ANALYSIS
Rather than sending Gray out for a minor-league rehab assignment after he tossed 54 pitches in a three-inning simulated game Wednesday, the Cardinals saw enough from the veteran right-hander to feel comfortable having him return from the IL for his next outing. According to Jones, Thompson won't be available out of the bullpen Sunday against the Marlins or in Monday's series opener with the Phillies just in case Gray suffers a setback leading up to Tuesday's game, but Thompson looks like he'll be headed for a relief role before long. Since he isn't yet fully ramped up, Gray is expected to be limited to 65 pitches Tuesday, so Thompson could even be called upon to pitch an inning or two once the former exits his start. After faring respectably upon joining the St. Louis rotation over the final two months of the 2023 campaign, Thompson has struggled to carry any momentum into 2024. Over his first two starts, Thompson has given up eight earned runs on 11 hits and six walks while striking out nine over 10.1 innings.

Latest Fantasy Rumors
Pushing for 2024 rotation spot
PSt. Louis Cardinals
September 6, 2023
According to Katie Woo of The Athletic, Thompson's performance this season could put him in a strong position to earn a rotation spot in 2024.
ANALYSIS
Miles Mikolas is the only established starter for St. Louis heading into 2024 after he inked an extension in March, and Thompson's 3.60 ERA through five starts potentially lines him up to enter spring training as a favorite for the rotation. Dakota Hudson, Drew Rom and Steven Matz, who is out with a lat injury, will also be in the mix, but Thompson could have a leg up if he's able to pitch well over the final month of the season.

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.
