Seattle Mariners explore trade of right‑hander Emerson Hancock

Seattle is reportedly willing to move right‑hander Emerson Hancock as part of a roster re‑balance aimed at adding more offense. Hancock, 27, is under team control through 2030 and is earning $793,300 this season after posting a breakout 3.16 ERA, better than his projected numbers. The club also mentioned veteran Luis Castillo as a possible trade piece, though his $22.75 million salary this year and the following season makes him a less attractive option for other teams.

The Mariners have six healthy starters—Logan Gilbert, George Kirby, Bryan Woo, Bryce Miller, Luis Castillo and Hancock—plus top prospects Kade Anderson, Ryan Sloan and recovering pitcher Logan Evans, giving them depth to consider a starter trade. Sources indicated the Chicago Cubs could be interested, as they are seeking right‑handed pitching while looking to add hitters such as Seiya Suzuki, Matt Shaw or Kevin Alcántara. The trade deadline is Aug. 3, and any move would be aimed at boosting the offense while maintaining pitching depth.
