The fantasy baseball landscape is ever-changing, and this week's risers and fallers for Week 5 of the 2025 season reflect that dynamic. Leading the charge is Pete Crow-Armstrong of the Chicago Cubs, who has dazzled with a .284 batting average, five homers, and league-leading speed on the bases, with 12 stolen bases. Meanwhile, Brice Turang of the Milwaukee Brewers has emerged as a surprise contributor, showcasing a .321 batting average and significant power with three home runs to complement his usual speed.

On the pitching side, Andrew Heaney has been a revelation for the Pittsburgh Pirates with a 1.72 ERA and 0.77 WHIP over five starts, hinting at a potential sell-high opportunity for fantasy managers. Conversely, Mike Trout of the Los Angeles Angels is struggling with a .177 batting average, raising concerns about his long-term viability. Anthony Volpe of the New York Yankees is also underperforming, hitting just .202, putting managers in a tough spot. As the season progresses, monitoring these trends will be crucial for fantasy success.
