11:22am: The teams are likely to complete a trade today, according to MLB.com's Steve Gilbert. Eichhorn and another player would go to Detroit and the D'Backs would take on most of Galarraga's $2.3MM salary.
9:24am: The Diamondbacks are 'likely' to acquire Armando Galarraga from the Tigers, according to Jon Heyman of SI.com (on Twitter). Nick Piecoro of the Arizona Republic reported over the weekend that the D'Backs were making a "strong push" for the right-hander and were exchanging names, including Kevin Eichhorn's, with Detroit.
The Nationals do not appear to be interested in Galarraga and the Indians aren't likely to get involved. The Pirates could have interest in the 29-year-old Venezuelan, though. Tigers GM Dave Dombrowski has said he's 'confident' he'll find a taker for Galarraga, who was designated for assignment to create roster space for Brad Penny last week.
The Tigers and D'Backs have exchanged a number of pitchers in the past 13 months. Max Scherzer and Daniel Schlereth arrived in the Motor City in the December, 2009 deal that sent Edwin Jackson to Arizona. Six months later, the Tigers sent Dontrelle Willis to the D'Backs for Billy Buckner. Those deals, however, were completed under former D'Backs GM Josh Byrnes.
