The Brewers announced that they claimed infielder Josh Wilson off of waivers from the Diamondbacks (on Twitter). In a corresponding move, the Brewers moved Takashi Saito to the 60-day DL; their 40-man roster is now full.
The D'Backs designated Wilson for assignment on Monday. The journeyman infielder has a .227/.280/.315 in parts of five seasons with the Marlins, Nationals, Rays, D'Backs, Padres and Mariners. Though he's primarily a shortstop, Wilson has appeared at every infield position and has pitched in three MLB games. GM Doug Melvin told Tom Haudricourt of the Journal Sentinel that the Brewers wanted Wilson's right-handed bat and versatility.
Note that the Brewers have have not claimed Josh Fields from Colorado.
