8:59am: The Astros will receive center fielder Jordan Schafer, southpaw Double-A starter Brett Oberholtzer, righty Double-A starter Paul Clemens, and righty Triple-A reliever Juan Abreu, tweets ESPN's Jayson Stark. None of the three pitchers are top 50 prospects, but they did rank ninth, 26th, and 27th respectively for the Braves on Baseball America's preseason rankings.
8:46am: The Braves acquired center fielder Michael Bourn from the Astros for four minor leaguers, tweets Ken Rosenthal of FOX Sports. He says the deal is done and will be announced shortly. Ken Davidoff of Newsday tweets that the Braves will receive money in the deal as well.
Bourn, 28, is hitting .303/.363/.403 in 473 plate appearances, and he leads MLB with 39 steals. The Scott Boras client has $1.45MM remaining on his contract this year and is arbitration eligible for 2012 before hitting free agency. The Astros' outfield purge continues, as they sent Hunter Pence to the Phillies on Friday.
