Wang, 33 next week, threw 12 scoreless innings for Chinese Taipei in the World Baseball Classic earlier this month. A number of teams scouted him during the event and had interest in signing him, including New York. He was at the team's spring training complex in Tampa to throw some bullpens and audition for a job earlier this week.
From 2006-07, Wang went 38-13 with a 3.67 ERA for the Bombers, finishing second to Johan Santana in the 2006 AL Cy Young voting. He hurt his foot running the bases during interleague play in 2008 and tore his shoulder capsule in 2009, injuries that have limited him to 231 2/3 innings from 2008-12 with New York and the Nationals.
The Yankees had been looking to sign a veteran starter for Triple-A depth, which is where Wang fits in. They have six starters for five big league rotation spots -- CC Sabathia, Hiroki Kuroda, Andy Pettitte, Phil Hughes, Ivan Nova and David Phelps -- but injuries will inevitably pop-up. Hughes has already battled a back injury in camp.
