As April heads towards its conclusion, many fantasy baseball managers are looking to bolster their rosters. This week’s waiver wire adds focus on under 40% rostered players who are making waves. Chandler Simpson, with undeniable speed, might not bring power but can significantly impact stolen bases. Pavin Smith is on fire, boasting an impressive .408 batting average and standout power metrics, making him a must-add for those in need of offensive boosts, especially against right-handed pitching.

Caleb Durbin is stepping up for Milwaukee, offering potential steals and a solid batting average, while Heston Kjerstad is warming up for Baltimore, showcasing power with three homers in six games. Carson Kelly has become a crucial asset in the Cubs lineup, leading catchers with a remarkable start. Lastly, pitchers Chase Dollander and Andrew Abbott are proving their worth, providing solid strikeout numbers that could help elevate fantasy rotations.
