The 2025 fantasy baseball season is in full swing, and savvy managers are already eyeing potential bust candidates as we approach the second half. Players like Zach McKinstry and TJ Friedl have shocked many with their performances, but underlying metrics hint at possible decline. With McKinstry's regression evident in his poor xwOBA and Friedl's alarming hard-hit rate, it may be wise to sell high while their values are inflated. Similarly, Ceddanne Rafaela's impressive numbers mask a decline in batting performance. Jeremy Pena's return from injury presents a brief window for a trade if someone still views him as a top-tier talent. Finally, Sal Frelick's contact-heavy approach is unlikely to sustain his current production, urging fantasy managers to seek out trades now.
