Luis Castillo delivered a quality start, allowing two earned runs on four hits and one walk while striking out five over seven innings in Tuesday's 3-2 loss to the Athletics.
Fantasy Impact
Despite a strong performance, Castillo's efforts weren't enough to secure a win, leaving his record at 11-12. His season-long metrics, including a 3.66 ERA and a 1.16 WHIP, continue to make him a reliable option in fantasy rotations, though his win-loss record might not reflect his effectiveness due to inconsistent team support. Castillo's ability to maintain a high strikeout rate and a solid ERA should keep him relevant in all fantasy formats, even if the Mariners' lineup struggles to provide run support.
Luis Castillo earned a win Wednesday, allowing two earned runs on six hits and two walks while striking out four over 5.2 innings as the Mariners topped the Rays 6-2.
Fantasy Impact
This performance slightly improves his season ERA to 3.65 and WHIP to 1.17, maintaining his status as a reliable fantasy option. Despite a mixed win-loss record now standing at 11-12, his solid K/9 rate of 9.1 and a decent FIP suggest better underlying skills than his win-loss record might indicate. Fantasy managers should continue to view Castillo as a strong rotation piece, especially in strikeout categories.
Luis Castillo racked up nine strikeouts but allowed five earned runs over six innings in the Mariners' 6-5 victory over the Giants on Friday.
Fantasy Impact
Despite the high strikeout total, Castillo was hit around, yielding six hits in his outing. This performance slightly tarnishes his otherwise solid season metrics, including a 3.66 ERA and a 1.16 WHIP. His ability to avoid walks was a positive takeaway, as he issued none during the game. Looking ahead, Castillo's high strikeout rate continues to make him a valuable asset in fantasy leagues, though his susceptibility to the occasional rough outing can be a concern for risk-averse managers.
