4:36pm: Schulman notes that excepting Glen Perkins, whom the Twins are unlikely to trade, the interesting reliever for the Giants in Minnesota's bullpen is Casey Fien. However, Schulman doesn't know whether the righty, who's posted a 3.55 ERA in 38 appearances, is available.

11:33am: Elder, a Giants scout, was in Minnesota last night to see the Twins' bullpen rather than Chamberlain, tweets Henry Schulman of the San Francisco Chronicle. Casey Fien,Jared Burton, Brian Duensing, and Josh Roenicke appeared for the Twins, with Burton and Duensing struggling.

10:30am: The Braves and Giants have an interest in Yankees reliever Joba Chamberlain, a pair of American League talent evaluators told George A. King III and Dan Martin of the New York Post. The Braves' Jim Fregosi saw Chamberlain Friday night, while the Giants' Lee Elder attended last night's game "exclusively to watch Chamberlain."

Chamberlain, 27, has a 5.75 ERA, 9.7 K/9, 4.4 BB/9, 1.77 HR/9, and 35.5% groundball rate in 20 1/3 innings this year. He missed most of May with an oblique strain. Chamberlain has worked at 95-97 miles per hour as of late and seems a good candidate for a change of scenery. Once an untouchable starting pitching prospect, Chamberlain is in his contract year and isn't expected to be with the Yankees next season. The Braves are known to be in the market for relief help; they last matched up with the Yankees in a minor trade in November 2010.
