The Yankees' interest in reliever Brian Fuentes could peak in the coming weeks as they look to fortify their bullpen, according to a report in The Denver Post. Joba Chamberlain, New York's lone reliable bridge to Mariano Rivera in the bullpen, will officially join the team's rotation on Tuesday. Fuentes is 0-2 with 6 saves and a 2.78 ERA in 22.2 innings of work for the Rockies this season.
