MLB Trade Rumors directed my attention to this post by Dan Connolly of the Baltimore Sun, who says the Orioles are "going hard" after Zack Greinke.
The Orioles surprised nearly everyone by getting off to a hot start this season and enter play Friday at 44-38. They're in second place in the AL East and if the season ended today they'd hold the league's second Wild Card. They're winning despite the fact that three of their primary starting pitchers (Jake Arrieta, Brian Matusz and Tommy Hunter) are all carrying ERAs above five.
Connolly also says, however, that the Orioles don't want to trade young pitching. They're still looking to the future and don't want to mortgage that by trading top prospects for help in 2012.
If the Orioles aren't willing to trade prospects for pitching, then I'm not sure how they can say they're "going hard" in this case. The Brewers aren't going to trade Greinke for scrap pieces or bad contracts, so unless the Orioles alter their approach it's hard to believe anything will come of this.
At any rate, though, having the Orioles as another interested party can only help raise Greinke's value if the Brewers decide to deal him.
