The Mariners are open to trading Luis Castillo, but they haven't received the sort of offers they were hoping to get.

Soon after starting pitcher Max Fried signed with the New York Yankees on an eight-year, $218 million deal, there were rumors that the Mariners and Boston Red Sox were engaged in trade talks involving Seattle starter Luis Castillo and Boston first baseman ...

The Seattle Mariners have depth in their rotation and need a bat. Enter the Baltimore Orioles, who are losing their ace, Corbin Burnes.

The Mariners have an opportunity to use some of their excellent starting pitching depth to improve the offense but the team has doubts.

Interest in Castillo increased significantly after the New York Yankees signed free-agent lefty Max Fried to an eight-year, $218 million contract, a Mariners source said. Castillo, 32, is owed less than one third that amount — $68.25 million over the next three years.

The Seattle Mariners entered the offseason with clear needs to address. Yet another whiff at second base has left them looking for almost an entirely new infield.
