The Florida Marlins appear ready to trade pitcher A.J. Burnett, and possibly third baseman Mike Lowell, with the Orioles and Red Sox making serious bids, according to sources. Burnett could be traded before his next start, which is Tuesday. "It almost seems imminent something is going to happen,'' a source close to the situation said Sunday. Burnett and Lowell flew with the team to Arizona after the Marlins' 8-4 loss to the Phillies on Sunday. A multi-player deal with the Orioles would be the Marlins' preference if the Orioles agree to take Lowell. Boston has offered a package that includes right-hander Bronson Arroyo. But "that could change with a phone call,'' according to a source who said about four other teams are interested. The Marlins are attempting to package Lowell in any deal involving Burnett. Talk of a three-way trade with Boston and San Diego was reported Sunday with third baseman Sean Burroughs and Arroyo among the players headed to Florida. Burnett and Lowell would wind up in Boston. A report out of the Baltimore area said the Orioles could make the deal if they would accept Lowell as part of the package for starting pitcher Hayden Penn (recently returned to Class AA), relievers Steve Kline and Jorge Julio and outfielder Larry Bigbie. Burnett, who is 5-6 with a 3.64 ERA and will be a free agent at the end of the season, appears unfazed by the reports. "I don't think it is going to happen," he said Sunday.
