2023 Fantasy Outlook
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. Read Past Outlooks

Heads to Triple-A
The Cardinals optioned Thompson to Triple-A Memphis on Tuesday, Katie Woo of The Athletic reports.
ANALYSIS
Guillermo Zuniga will fill the vacancy in the Cardinals bullpen ahead of Tuesday's series opener against the Angels. Thompson had been lit up for five earned runs on four hits and five walks over his last three appearances covering just 2.1 innings. He'll get stretched out in a starting role at Memphis.

Recent RotoWire Articles Featuring Zack Thompson See More

James Anderson pinpoints relievers and potential relievers from the minor leagues who could develop into the next great fantasy baseball closer, including recent Angels draftee Ben Joyce.

James Anderson ranks rookie pitchers for 2023 value within tiers, and Astros righty Hunter Brown is one of four pitchers in the top tier.
2021 Fantasy Outlook
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.
