The White Sox have acquired Brett Myers from the Astros, a source tells Ken Rosenthal of FOX Sports (via Twitter). Houston announced that they will receive right-hander Matt Heidenreich, left-hander Blair Walters, and a player to be named later for the pitcher. The Astros will also send cash to Chicago, according to the White Sox.

The White Sox are on the hook for just $1MM of the $4.45MM still owed to Myers this year, according to Dan Hayes of CSNChicago.com (via Twitter). Chicago also received money to go towards Myers' salary or possible buyout for next sesaon.

Myers, 31, has a $10MM option for 2013 that will vest if he finishes 45 games and doesn't end the season on the disabled list. To date, the closer has finished 29 games with 35 appearances in total. Rosenthal notes (via Twitter) that Myers has a $500K bonus in his contract for being traded, but it's not yet known which team will pick up the tab.

The veteran has been linked to a handful of clubs recently including the Cardinals and the Mets but the White Sox weren't among the teams rumored to be interested. The right-hander has posted a 3.52 ERA with 5.9 K/9 and 1.8 BB/9 for the Astros this season.

Astros GM Jeff Luhnow has extremely busy this week, having just completed a ten-player swap with the Blue Jays. That deal brought six players to Houston including four minor leaguers and a player to be named later. In total, Luhnow has replenished the Houston farm system with eight prospects through these two deals.

Heidenreich, 21, has a 3.95 ERA with 5.7 K/9 and 1.5 BB/9 in 18 Single-A and Double-A starts this year. Houston announced that the former fourth-round pick in the 2009 draft will be assigned to Double-A Corpus Christi. The 6'5" right-hander boasts a fastball in the low-to-mid 90s and will likely fill out in the years ahead as he weighs in at just 185 pounds.

Walters, 22, has split time between Single-A and Advanced-A this year, posting a 3.96 ERA with 8.6 K/9 and 2.0 BB/9. Prior to this season, Baseball America had the left-hander ranked as the No. 26 prospect in the White Sox organization.
