According to Baseball Digest Daily, the Diamondbacks acquired reliever Jon Rauch from the Nationals for second baseman Emilio Bonifacio.
Bonifacio was ranked sixth among D’Backs prospects heading into the season. He’s hitting .302/.348/.387 in Triple A currently. He’s incredibly fast and plays above-average defense.
The D’Backs get a fine late-inning reliever in Rauch; I thought Jim Bowden would ask for more. Rauch is signed cheaply through 2010 and has been an above average reliever for several years now.
