LAKELAND, Fla. -- The Yankees dipped into their recent past Saturday when they officially signed Chien-Ming Wang to a minor-league contract.

Wang, who had been working out at the Yankees' minor-league camp, rejoins the organization he pitched for from 2005-09. Featuring a power sinker, he went 55-26 with the Yankees, going 19-6 in 2006 and 19-7 in 2007.

Wang, who turns 33 next Sunday, has been a shell of his former ace self since suffering a serious foot injury while running the bases in Houston on June 15, 2008. He was 8-2 at the time.

After undergoing major shoulder surgery in July 2009, he pitched for the Nationals in 2011 and 2012, going 2-3 with a 6.68 ERA in 10 games last season.

The Yankees hope Wang can give them some veteran insurance at Triple-A Scranton/Wilkes-Barre. He threw 12 scoreless innings for Chinese Taipei in the recent World Baseball Classic.

"He pitched well in the WBC,'' Joe Girardi said. "This guy has had success before.''
