The 2025 MLB season has seen some surprising underperformers, including notable players like Salvador Perez and Andrew Vaughn, both of whom are grappling with low averages yet exhibit promising advanced metrics. Perez, despite a rough start, maintains a strong barrel rate and hard-hit percentage, hinting at a potential turnaround. Vaughn's stats suggest he's been unlucky, as his underlying performance metrics indicate he's trending positively despite a dismal batting average.

Brandon Lowe and Marcus Semien also highlight the unpredictability of baseball; Lowe's early-season power fizzled out but remains a key contributor in terms of potential homers and RBIs. Semien, known for his consistency, is also primed for a resurgence as he shows signs of improvement. The article emphasizes that advanced analytics are essential for discerning hidden value in players who may be on the verge of breaking out, providing a lifeline for fantasy managers.
