The Seattle Mariners want to add and it sounds like they are willing to potentially flip a starter.
USA Today's Bob Nightengale reported that Seattle is willing to trade one of its "prized" starters, with Luis Castillo being the "most likely."
The Seattle Mariners are letting teams know that they are willing to trade one of their prized starters for a back-end reliever and right-handed hitter, most likely Luis Castillo. They not only have a surplus of starters at the big-league level with a six-man rotation, but they have the finest pitching prospect in baseball with Kade Anderson. Andersonβs numbers are mind-boggling at Class AA where he has a 1.36 ERA and .160 opponentβs batting average in 14 starts."
Castillo is a three-time All-Star with a 4.93 ERA in 18 total appearances this season across 87 2/3 innings of work. He has a career 3.63 ERA and would be a big help for a club in need of pitching down the stretch. The Mariners need offense and have a surplus of pitching. There have been rumors for years at this point about Seattle potentially flipping a hurler. Could this finally be the summer a move gets done?
