According to Jayson Stark, Rodrigo Lopez is "expected to sign" to sign with either the Braves, Mets or Rockies by the end of the weekend. If he signs with the Braves, he'd be given a non-roster invitation to Spring Training, and if he made the club (really?) he would receive some bonus money.
As someone who watched Lopez pitch in for the DBacks in 2010, we want absolutely no part of this guy. He did pitch 200 innings, but that's only because Arizona had no better options and didn't want to kill their bullpen even more. He'd just be taking away starts from someone in Gwinnett, and he's not good enough to even be our long-man in the 'pen. We can only hope he goes to the Mets.
Lopez was part of the Braves organization at the end of 2008, signing at the end of August, a year to the day after having Tommy John surgery. He appeared for Rome and the GCL Braves, but was released a month later. So he has some history with the Braves. He was a longtime Orioles pitcher, so Frank Wren and many other transplanted Orioles execs are familiar with him.
