The Chicago Cubs announced today that they traded righthanded relief pitcher Jermaine Van Buren, 25, to the Boston Red Sox for a player to be named later. Van Buren had a 1.87 ERA in 53 innings for double-A West Tenn in 2004 and a 1.98 ERA in 54.2 innings for triple-A Iowa in 2005, serving as the closer for both teams. He got into 6 games for the big league club in 2005, allowing 2 runs in 6 innings (though he walked 9, which was inconsistent with his recent minor league performance).
