As the halfway point of the MLB season approaches, identifying pitching bust candidates becomes crucial in the fantasy baseball landscape. Players like Kodai Senga, Grant Holmes, and Seth Lugo show significant discrepancies between their surface stats and underlying metrics, indicating a potential decline. Senga's high WHIP and reliance on his splitter raise concerns about his sustainability, while Holmes' increased innings pitched could lead to fatigue. Gavin Williams displays promising strikeout numbers, yet struggles with walks, making him a sell-high candidate. Lugo's recent performance suggests regression is imminent, especially with 17 home runs allowed. Trading these pitchers before their values decline could provide a critical edge in fantasy leagues.
