Chuck Knoblauch takes shot on Twitter at honor for Andy Pettitte

NEW YORK (KTRK) -- Former Astros pitcher Andy Pettitte is set to join the all-time greats in Yankees history.

The Yanks will retire Pettite's #46 on August 23. It's a fitting honor for a five-time World Series champion.

Pettitte's son, Josh, was first to break the news on Twitter

But then a former teammate of Pettitte's took a shot, also using social media. Former Yankee and Bellaire Cardinal Chuck Knobluach tweeted, 'Congrats to 46. Yankees retiring his number. Hopefully they don't retire it like his HSH testimony.'

Along with Pettitte, the Yankees are also retiring the jerseys of Bernie Williams and Jorge Posada.
