They were backed into a corner with Simon and the team cannot have a bullpen that has so much youth in it. The Orioles could end up keeping Rosario and some stability was a nice addition to the bullpen. Uehara is a low key guy that will be fine with either role and does not seem to be a vocal person that impact the club.
Kevin Gregg is not the ideal choice considering that it is basically a three year deal, if attains a significant bullpen role. I do not like it, but it beats going for Soriano for 3 years and 24 million, which is what is being told in circles.
The deal might blow up in the Orioles face, but the risk between these two and Gonzo should help stabilize the bullpen with all three remaining healthy. I like Gonzo and feel that he can bounce back. The bullpen sets up rather nicely because of its versatility, but I feel the need for another left handed pitcher is still a need for the bullpen.
Brian Fuentes, Will Ohman, Tim Byrdak, or Dennys Reyes would be worthy options for that role.
