The man who tossed a 27-out perfect game was designated for assignment by Detroit after acquiring Brad Penny. While Detroit can release Galarraga for just 30 days termination pay at this point, the Tigers would be better served to get some value for him in a deal, and it looks like Arizona is willing to comply.
Galarraga appears to be a better fit in the NL anyways, as he doesn't have an overwhelming advantage in his game. He is simply an OK starter, having posted a 4.49 ERA in 24 starts (144 1/3 innings) last season. He doesn't particularly have great control or whiff bats, so his value comes from being essentially average -- an innings eater who won't embarrass himself on the mound.
Given Arizona currently has a starting five projected to be Ian Kennedy, Joe Saunders, Daniel Hudson and then a battle between Barry Enright, Kevin Mulvey and Zach Duke. There is absolutely room at the back of the rotation, and the name that is popping up in trade discussions is Kevin Eichhorn.
Eichhorn finished 2010 as a 20-year-old by pitching predominantly in the rookie league although he did have one start apiece in both low and advanced-Class A. He finished the year with an overall ERA of 5.00 in 15 starts, but his 1.9 BB/9 and 8.4 K/9 do portend for future success.
