Jake Arrieta was Baltimore's Opening Day starter and holds significant promise, but his statistics are not all that impressive. He is 19-23 with a 5.27 ERA for the Orioles in his career, including 3-9 with a 6.13 ERA this season. Some within the Orioles organization believe that the team would be foolish to give up on him, according to Major League sources. The problem is that Baltimore wants to improve their playoff chances ahead of the July 31 non-waiver trade deadline without dealing any of their top prospects. That means Arrieta could be in play. "I think they would move him," one rival executive said. "They don't have much choice if they want true upgrades and won't trade their premium guys."
