From Ken Rosenthal:
The Reds resolved their outfield logjam by trading Wily Mo Pena to the Red Sox for right-hander Bronson Arroyo, but it's not out of the question that they would move Austin Kearns if they got the right pitcher in return.Chris Denorfia, a Triple-A player often compared to the Brewers' overachieving Brady Clark, could step in for Kearns, though some view Denorfia as more of a fourth outfielder while Kearns is a potential No. 5 hitter.
The Reds' depth would be compromised if they traded Kearns, especially if Ken Griffey Jr. were injured, but Ryan Freel, Jacob Cruz and Quinton McCracken still would be in the mix, and outfielders are easier to find than pitchers.
Above that there's an item about Francisco Liriano and how his service time is being wasted by putting him in the bullpen.
I'd give up a hell of a lot more than Austin Kearns to get Liriano, and I hope Krivsky has at least explored that opportunity.
