Ken Rosenthal of Fox Sports is reporting that Joe Mauer has been placed on trade waivers.

The Minnesota Twins placed catcher Joe Mauer on trade waivers Tuesday, FOX Sports' Ken Rosenthal reported, citing a major league source. Rosenthal said it would be an act of discipline for the Boston Red Sox to pass on Mauer, "a player who once was their Holy Grail," especially after dumping more than $245 million in contracts in a trade with the Los Angeles dodgers last week. Mauer, a 29-year-old former MVP and regular All-Star, has about $142.5 million remaining on his contract – likely more than Boston is willing to take on.

What does this mean for the Minnesota golden boy? It means he is available to be traded for the right deal but would have to pass through waivers before the deal could be done. After a team makes a claim they would have two days to work out a deal. If no deal is made he will remain with the Twins.

Mauer also has a full no-trade clause in his contract. If a deal is made, Mauer would have to approve the trade.
