The Cubs, aggressively pursuing a blockbuster trade for Orioles shortstop Miguel Tejada, are willing to part with a top starting pitcher, most likely right-hander Mark Prior, sources tell FOXsports.com. The talks are stalled, a source says, over the Cubs' insistence that the Orioles give up left-hander Erik Bedard along with Tejada if they want Prior ? and the Cubs' refusal to include top outfield prospect Felix Pie or a top pitching prospect in return. The Cubs and Orioles also have engaged in three-way discussions with the Red Sox in which Tejada would go to the Cubs and Ramirez to the Orioles, according to another source. The package the Sox would receive is unclear, but conceivably could include Prior, shortstop Ronny Cedeno and center fielder Corey Patterson. Whatever the details, a three-way deal would appear to be a longshot, and no other deal appears close. The Red Sox would need to give the Orioles pitching along with Ramirez if they wanted Tejada in a straight, two-team trade. The Angels' offers for Tejada have been insufficient, sources say. The Orioles are concerned that they would be losing too much offense if Prior was their principal acquisition in a Tejada deal. The Red Sox share the same reservation about trading Ramirez for anything other than a hitter of Tejada's caliber. The Orioles and Cubs have been talking for at least a week. While the teams completed a trade involving outfielder Sammy Sosa last off-season, that deal was essentially a salary dump by the Cubs. A Tejada deal would be more difficult to accomplish.
