Dustin McGowan

According to various sources, including the Toronto Star's Richard Griffin, the Toronto Blue Jays have placed pitcher Dustin McGowan on the 60-day DL.

For the much-maligned McGowan, this is a major blow to yet another comeback attempt. In fact, this could be the death knell for what was once a very promising career.

According to Jon Morosi of FOX Sports, the Blue Jays are believed to have interest in signing relievers Matt Guerrier and Jesse Crain.

Guerrier was not offered arbitration by the Twins, so he is now a free agent. In 2010, a campaign where he made $3.15 million, experts peg him to make no more than four to five million next season.
