The Seattle Mariners have considerable depth in their starting rotation, which could lead to a trade that improves another part of the roster.

Luis Castillo and Robbie Ray are locked in for the foreseeable future on massive contracts, while Logan Gilbert and George Kirby proved this past season that they can be capable Major League starters.

It's possible the Mariners could look to trade Chris Flexen, who multiple clubs inquired about at this summer's deadline. Flexen had his $8 million option for 2023 vest after posting a 3.73 ERA and 95 strikeouts in 137 2/3 innings.
