Yankees starter Andy Pettitte is expected to once again announce his retirement from the MLB at some point today. The 41-year-old ace had retired in 2011 only to rejoin the team a year later for the 2012 season. Of his 18 years in the major leagues, Pettitte spent 15 of them wearing pinstripes plus a three-year stint in his native Houston playing for the Astros.

Pettitte will get a fitting farewell for his final game in Yankee Stadium, which he'll pitch this Sunday; his final outing coincides with Mo Day, a special celebration honoring fellow retiree Mariano Rivera. The two pitchers set the wins/saves record in the MLB, with Rivera saving 72 of Pettitte's wins and counting, 23 more than other pitchers saved by Rivera. "It's awesome. He's awesome," Pettitte gushed in 2009. "What can you say? I feel honored to have been able to play with him for as long as I have. He's a tremendous person and a tremendous baseball player."

The three-time All Star logged 255 career wins and Pettitte counts five World Series rings in his collection, all of them with the Yankees. He also holds the record with 19 wins in the postseason, more than any other pitcher. Also fitting: Pettitte will make his final career start against the Astros in Houston.
