AL East Notes: Red Sox, Johnson, Yankees, Ishikawa

Let's take a look at the latest news and notes involving the American League East:

• The Red Sox are open to trade market upgrades in the bullpen and at third base, tweets ESPN's Buster Olney.
• One name on Boston's list of bullpen trade targets is the White Sox's Matt Thornton, sources tell Ken Rosenthal of FOXSports.com (Twitter link). The Braves also have "limited" interest in the left-hander.
• Josh Johnson, set to become a free agent at the end of the season, has seen injury and poor performance affect his value to the point where it is difficult to see the Blue Jays pursue a multi-year deal with him, writes the Toronto Star's Richard Griffin. Johnson may be forced to accept a qualifying offer from the Blue Jays, assuming he receives one, to rebuild his value for 2014, opines Griffin. 
• The Phillies' Michael Young and Carlos Ruiz both could be on the Yankees' radar as they have a scout in Philadelphia today, tweets Jayson Stark of ESPN.
• The recently-released Miguel Olivo is not on the Yankees' radar, but first baseman Russ Canzler, who was designated for assignment yesterday, might pique their curiosity, according to the New York Post's Joel Sherman (Twitter links).
• Earlier today, the Yankees added first base depth by claiming Travis Ishikawa off waivers from the Orioles. O's Executive Vice President Dan Duquette told reporters, including Roch Kubatko of MASNsports.com, he acquired Eric Thames from the Mariners last week knowing he could lose Ishikawa to another team.
