Seattle Mariners Reportedly Turned Down Recent Trade Offer For All-Star Luis Castillo

Without knowing the specifics, a lot of that would seem to check out. The Mariners do need offensive help after the injuries to Bliss and Robles and teams certainly know that. However, the M's aren't really in a position to trade Castillo, either. While they'd undoubtedly like to have the payroll flexibility that a trade would provide, they can't afford to whittle away at their pitching depth, especially while George Kirby is still on the mend from his right shoulder inflammation.

Castillo is of to a solid start for the M's as well, going 1-1 with a 2.12 ERA. An All-Star in 2023, he's a three-time All-Star in total. Lifetime, he's 74-77 with a 3.54 ERA over nine seasons with the Cincinnati Reds and Mariners.

Castillo will make his return to Cincinnati on Tuesday night when the M's take on the Reds at Great American Ball Park. First pitch is set for 3:40 p.m. PT.

Both teams enter the series at 8-8. The Mariners have won four straight games after sweeping the Texas Rangers.
