Veteran pitchers like Zac Gallen and Luis Castillo are causing concern among fantasy baseball owners. Gallen has struggled with a 6.62 ERA in the last month and a 5.75 ERA for the season, leading to calls for his removal from rosters. Despite a drop in performance, Castillo's historical value suggests he might still be worth holding onto, especially if he can turn it around post-All-Star break. Other notable mentions include Camilo Doval, who's showing inconsistent form but has upside, and Kenley Jansen, whose save opportunities remain intact despite high ERA numbers.

Roman Anthony, a top prospect, is still worth holding onto due to his potential, while Corey Seager’s underlying metrics indicate he might rebound soon, making him a buy-low candidate. The episode emphasizes the importance of trading struggling players if possible, and being cautious with roster decisions as the season progresses.
