Morning roundup: Orioles likely to be buyers at trade deadline

The Orioles will be buyers after losing Jason Hammel, and the White Sox could make a big move at the deadline.

• The Orioles will buy at the deadline, as pitcher Jason Hammel will undergo knee surgery. The team is willing to deal any prospect beside Dylan Bundy and Manny Machado. They may not have the pieces to go after Zack Greinke, but the Orioles are interested in Jason Vargas, Joe Blanton and Juan Pierre, according to FoxSports.com's Ken Rosenthal.
• Chase Headley is likely to be moved, but Carlos Quentin is likely to stay put in San Diego, said Rosenthal.
• If the Marlins do sell, Anibal Sanchez, Omar Infante and Carlos Lee could be on the block.
• The White Sox could make a play for Zack Greinke, but they don't really have the right pieces in their farm system, reported Rosenthal.
• Yankees GM Brian Cashman doesn't like the high asking prices on the free-agent market, according to nj.com's Marc Craig. Because of that, it seems unlikely the Yankees will seek help in left field, where they are playing Raul Ibanez and Andruw Jones.
• With Sergio Santos out for the rest of the year, the Blue Jays will trade for a reliever if they are still in contention, tweeted FoxSports.com's Jon Morosi.
• The Rangers have scouted Justin Upton and Joe Saunders, and the Dodgers are scouting Ryan Dempster and Matt Garza, said Morosi.
