In the midst of a disappointing 2026 season thus far, the Seattle Mariners are reportedly fielding interest in three of their top starting pitchers. The Mariners have reportedly also listened to offers for Emerson Hancock and Luis Castillo ahead of Monday's trade deadline. A 2023 All-Star, Kirby owns a 3.65 ERA over his five MLB seasons, all of which have been spent in Seattle. Hancock, 27, has been a revelation for the Mariners this season after posting a 4.81 ERA over his first three seasons. In 20 starts this season, Hancock is 6-5 with a 3.26 ERA, 1.04 WHIP and 102 strikeouts over 110.1 innings.
