AL East Notes: Bradley Jr., Blue Jays, Jay-Z

MLBTR would like to take a moment to send our deepest condolences out to the victims of the Boston explosions today. If you're in the Boston area and would like to help by donating blood, Mass General Hospital in Boston is accepting walk-ins beginning at 7am tomorrow morning. With apologies for how trivial the following will seem, here's some baseball-related news out of Boston and the rest of the AL East…

• Jackie Bradley Jr. is mired in an 0-for-20 slump, but the Red Sox were prepared for the possibility of such struggles when they decided to bring the 22-year-old north with the team, writes WEEI.com's Alex Speier. Manager John Farrell said Bradley has dealt with the adversity as well as the team could have expected.
• Blue Jays general manager Alex Anthopoulos told Shi Davidi of Sportsnet.ca that he's talking with other teams about an upgrade to his middle infield but doesn't anticipate a deal in the near future due to rival GMs' asking prices (Twitter link).
• Jay-Z's Roc Nation Sports company will not work with any sports talent agencies other than CAA Sports, according to Liz Mullen of Sports Business Journal (on Twitter). The agency will hire established agents in multiple sports as well as have its own employees (link). Jay-Z entered the world of sports representation in a big way in recent weeks, taking Robinson Cano away from Scott Boras.
