Week 4 of Fantasy Baseball features exciting prospects worth stashing as call-ups loom. Key prospects include Nick Kurtz of the Athletics, who boasts a staggering 176 WRC+ and leads the minors with seven homers, suggesting he’s ready for a major league opportunity. Roman Anthony from the Red Sox is also a top pick, showcasing advanced plate discipline and a 161 WRC+ this season, potentially providing the spark the struggling Red Sox need.

Power-hitting Coby Mayo of the Orioles has had a strong showing in Triple-A with three homers in the last week, but faces competition for a call-up. Agustin Ramirez of the Marlins, with impressive power-speed potential, remains a sleeper due to the team's current catching situation. Lastly, Jordan Lawlar of the Diamondbacks could capitalize on a roadblock in their lineup as he continues to excel at Triple-A, but his future is uncertain with Ketel Marte's imminent return.
