According to Ken Rosenthal on Twitter, the Jays have reached a tentative deal with the Mariners to acquire Brandon Morrow for Brandon League and a prospect. There has been speculation about who the prospect may be, if the rumours are accurate, but these do not appear to be based on anything substantial. League was a serviceable reliever with nasty sinking stuff, but Morrow gives the Jays a potential starter with middle-of-the-rotation upside. It will be interesting to see who the prospect is, because I don’t see how dealing Morrow helps the Mariners win 2010. Thanks to HippyGilmore and Mike Forbes for breaking the news.
