Spencer Arrighetti

Scouting Profile

Spencer Arrighetti profiles as a balanced mid-rotation arm. His 9.5 K/9 sits in the middle of the pack (68th percentile), backed by a 105 Stuff+ that reads as roughly league-average stuff. Command grades at the 2nd percentile (4.2 BB/9), shaky command, over a 6.5-inning average workload. Within the HOU rotation he grades as the 1st arm by strikeout rate — the staff’s top bat-misser.

2026 Strikeout Prop Outlook

For strikeout props the baseline lands near 6.9 Ks, but the daily number moves with the matchup: a lineup that whiffs more than average against right-handers pushes it up, a contact-heavy one pulls it down — the L3 opponent split is the single largest swing. Cold air and a pitcher-friendly park add roughly 0.2–0.6 K; a hitter’s park trims the ERA side. A steady 6.5-inning workload gives the counting stats room to accumulate.
