That doesnt confirm they believe that his breakout is fraudulent.
But they can see the numbers, they understand their roster and recognize when theyre sitting on a sell-high opportunity.
Hancock has been terrific compared to anything weve seen from him before this season.He owns a 3.16 ERA and a 1.01 WHIP with 97 strikeouts against 26 walks through 105 1/3 innings.
After years of looking like an underperforming former No.
6 overall pick, he changed his arm slot, reshaped his arsenal and introduced himself as a legitimate major league starter.
Its a truly great story.
Its also a great opportunity to have trade discussions.The Mariners arent trying to sell Hancock as a future ace.
Other clubs dont appear to view him that way, either.
His 3.72 FIP is already less impressive than his ERA, and his xERA sits more than a full run above his actual mark.
Those numbers dont erase what Hancock has accomplished,This is exactly when smart teams sell high.Hancock is earning only $793,300 this season and remains under club control through 2030.
That combination makes him one of the Mariners most appealing trade pieces.
Hes cheap, controllable and ready to take the ball every fifth day for a contender that needs rotation help immediately.
Luis Castillo is the obvious starter Seattle would prefer to move, but the value is vastly different.Castillo is owed $22.75 million next season.
The Mariners also have the rotation depth to make this move.
Logan Gilbert, George Kirby, Bryan Woo and Bryce Miller arent going anywhere unless its an absolute blockbuster.
Castillo remains capable of eating innings,Hancock gives Seattle a chance to address their needs without tearing apart the farm.And a contender with a right-handed hitter to spare could useThe return has to matter here.
If Hancock moves, the Mariners need an everyday hitter who can punish left-handed pitching and remain in the lineup against right-handers.
Ideally, that player also comes with multiple years of control.
