Diaz added seven strikeouts and four walks. He allowed a hit and walk to the first two hitters he faced before he settled in the rest of his outing of just 79 pitches. He is scheduled to face Arizona again in his next start.

Yilber Diaz was roughed up, surrendering seven earned runs on nine hits and one walk over just three innings in Monday's 10-4 loss to the Royals.

Fantasy Impact

This outing ballooned his ERA to 5.40, while his WHIP also took a hit, escalating to 1.40. Diaz's inability to strike out a single batter exacerbates concerns about his fantasy viability, especially given his modest season-long strikeout rate of 4.2 K/9. With such performances, Diaz is becoming a risky play in all fantasy formats, and managers might want to consider other options for more reliable starts. His current form suggests a potential demotion or role change could be imminent if improvements aren't seen quickly.
