St. Louis Cardinals: Right Fielder26 of 30Ben Jackson/Getty ImagesSt. Louis' first-round pick in 2020, Jordan Walker entered 2023 as one of the highest rated prospects in all of baseball. But after a respectable debut year with 16 home runs and a .787 OPS, these past two seasons have been disastrous. Walker has posted a .589 OPS, while providing what would be the worst right field defense in all of baseball, were it not for Nick Castellanos. At least he isn't costing them a ton of money, still a year away from becoming arbitration-eligible for the first time. He's also just 23 years old and plausibly could figure out this whole "hitting MLB pitching" thing soon.
