AL East Notes: Red Sox, Yankees, Boesch, Dickerson

As regular season baseball returns, let's have a look in at some links involving the American League East, which is the only MLB division to feature four teams with winning records:

• The Red Sox will emerge from the All-Star break down yet another bullpen arm, with reports emerging that Andrew Bailey will likely be lost for the season. In addition to making Boston's acquisition of Bailey look even less beneficial than it already did, the news could increase the likelihood that the Sox will return to the reliever market before the trade deadline. The team already moved to add two prominent names — Jose Contreras and Brandon Lyon — on minor league deals earlier today.
• Boston GM Ben Cherington says that Bailey's loss will "move the needle" in determining whether the team will look to pick up another reliever, reports WEEI.com's Alex Speier. He did maintain that the Red Sox have adequate internal options and said that he is disinclined to do anything major. "As I said when [Andrew] Miller went down, when a guy goes down you have to replace him somehow," said Cherington. "You hope that the guys are already here internally, but you've got to keep an open mind and continue to do that over the course of the next couple days."  
• Yankees GM Brian Cashman also discussed the deadline today, telling reporters including Jack Curry of the YES Network that his club has active in trying to work up a deal but that the trade market is "a tough one." (Twitter link.) Cashman described the market for offensive players as "an offensive offensive market," tweets Andy McCullough of the Star-Ledger. 
• There could be a structural reason for the trouble the Yanks are finding, writes Brian Costa of the Wall Street Journal. With the two-wild card system leaving more teams in contention longer, he reasons, New York is less able to utilize its deep pockets to take on late-year salary dumps.
• The reason that the Yankees dropped injured outfielder Brennan Boesch earlier today, his agent tells Dayn Perry of CBSSports.com, is not Boesch's ability. "The Yankees' decision to release Brennan Boesch is a matter of timing, not talent," said agent Brodie Van Wagenen. "Brennan's rehab on his shoulder is going well and he expects to be full strength and able to make a meaningful contribution to a major league team in August."
• After designating outfielder Chris Dickerson for assignment earlier today, the Orioles are hoping to work out a trade to get some value back for him, writes MLB.com's Britt Ghiroli. Manager Buck Showalter says that he believes Dickerson is a big league player who will catch on with another club. To complete a busy day for the O's, the club learned that it will likely go without backup outfielder Nolan Reimold for the rest of the year.
