A recent article by the MLB Trade Rumors explored possible teams that could acquire the veteran starting pitcher and potential returns the Seattle Mariners could get for the three-time All-Star.

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

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.

As prices for starting pitchers have swelled, the Mariners have received more calls from teams interested in starter Luis Castillo. Here's the latest.

The Seattle Mariners blew a sizable division lead last season as the team was ultimately overtaken by the AL West-winning Houston Astros. Despite buying at the trade deadline Seattle missed the playoffs for the 22nd time in the last 23 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.
