Scout’s note
Seth Lonsway is a 27-year-old lefty from St. Mary's, Ohio, a sixth-round pick in 2021 who reached the big leagues on August 29. His entire MLB line is one game and two strikeouts — a cup of coffee, still warm.
What he’s paid
Pre-arbitrationA market fact, not an engine read: what a club decided about him, on the season before this one. Figures from Cot’s, as of .

The deal 1 year (2026)
On the sheet: 1 y (26)
Regime read from his service time, not from the sheet — it does not project him past this season. Super Two eligibility is the top 22% of a class and can move this line in a way service time alone cannot see.
Cash and the tax hit are two different rulebooks and are never subtracted from one another — see the payroll board for his club, San Francisco Giants.
