What is the trade value of Triston Casas?
One value comp might be Tampa first baseman Yandy Diaz, who is included in this featured hypothetical trade at Baseball Trade Values:
https://www.baseballtradevalues.com/trades/181711
BTV assigns a surplus value of $29.9 million to four years of Casas and a surplus value of $23.4 million to Diaz, who is owed $10 million in 2025 with a 2026 club option for $12 million (no buyout).
Steamer projects a 25-year-old Casas with a 2025 WAR of 2.4 in 146 games and a 33-year-old Diaz with a 2025 WAR of 3.6 in 150 games.
The BTV hypothetical would send Diaz and six years of infielder Curtis Means to Seattle for a four=player package of a 20-year-old Top 50 prospect and three first-round draft picks (two disappointing and one in the 2025 draft).
The Red Sox are in a win-now mode without the fiscal constraints of the Rays, but would the Sox trade Casas and, say, five years of infielder Vaughn Grissom for the Seattle package? The aggregate BTV numbers match up.
Speaking of matching up ... Baseball Trade Values assigns Boston righthander Lucas Giolito and Seattle outfielder/DH Mitch Haniger identical negative trade values of $15.5 million.
Would the Red Sox be interested in Haniger's righthanded bat, perhaps as a platoon partner with Wilyer Abreu? Would the Mariners want Giolito as depth behind their touted five-man starting rotation?
Haniger has one year and $15.5 million remaining on his contract, according to Spotrac. Giolito is owed $19 million in 2025 with a 2026 mutual option for $14 million ($1.5 million buyout) if he pitches 140 innings in 2025. Giolito's contract also includes incentives for innings pitched each year.
Haniger's contract includes a $1 million assignment bonus that is typically picked up by the trading team, in this case the Mariners. The frugal Seattle front office might be unwilling to take on Giolito's 2025 salary and 2026 buyout on top of the assignment bonus.
Steamer projects Haniger with a 2025 WAR of a negative 0.1 in 105 games and Giolito with a 2025 WAR of 1.0 in 29 games, including 15 starts.
Someone has too much time on his hands this holiday season.π
