The New York Yankees, still in the market for pitching help, are stepping up their pursuit of free agent Justin Duchscherer, a baseball source told ESPN.com.

Duchscherer, 33, has a career record of 33-25 with a 3.13 ERA in eight seasons with the Oakland Athletics and Texas Rangers. He made the American League All-Star team as a reliever with Oakland in 2005 and again as a starter in 2008.
