We knew that the Boston Red Sox and Seattle Mariners were talking about a deal for M's pitcher Luis Castillo in the offseason, but Coley Mick of the Section 10 podcast made an interesting revelation about those conversations on Friday night.

Over the course of the last offseason, we knew that the Seattle Mariners and Boston Red Sox were talking about a possible trade involving Seattle Mariners pitcher Luis Castillo.

At the time, the Red Sox needed starting pitching help, and the Mariners were likely intrigued by the idea of acquiring offense while shedding some or all of Castillo's salary, which is about $24 million per season.

Based on reports, it seemed as if a lot of the conversation centered around Red Sox first baseman Triston Casas, who would have filled a first base hole for Seattle, but the Mariners weren't necessarily that interested in.

Well, we may have learned a little more about the nature of those conversations on Friday night, as popular Red Sox podcaster Coley Mick indicated that the Mariners were also interested in Red Sox utility player David Hamilton.

Now, it's unclear exactly what Mick meant by this, but it should be noted that the Section 10 crew is extremely plugged in and connected. The Mariners may very well have been interested in Hamilton, but it's likely that they wanted more than just him.

For reference, Hamilton is a light-hitting infielder who is hitting .200 this season, though he does have 20 steals.

Castillo has had an up-and-down season for Seattle, but he's been a reliable arm that would have helped Boston as well. He's gone 9-8 with a 3.76 ERA thus far.

Hamilton and the Red Sox will be back in action on Saturday afternoon when they take on the New York Yankees at 4:10 p.m. ET. Boston currently leads Seattle by one game in the battle for the second wild card spot.
