TAMPA — Add Andy Pettitte to the growing list of Yankees legends.

The Yankees will honor the popular lefty with Andy Pettitte Day on Aug. 23 at Yankee Stadium, in a ceremony prior to a game against the Indians, during which he will receive a plaque in Monument Park and have his No. 46 retired. It will be the 16th number so honored in franchise history.

Not everyone is happy for Pettitte, though.

Pettitte’s former teammate, Chuck Knoblauch, mocked the move on Twitter Sunday night. The retired second baseman wrote:

Knoblauch, like Pettitte, was mentioned in the Mitchell Report and eventually admitted to using HGH.

Josh Pettitte, one of the pitcher’s three sons, broke the news on Sunday when he announced the Yankees’ plans on Twitter.

Andy Pettitte, 42, joined Mariano Rivera in retirement following the 2013 season. In 18 big league seasons, Pettitte went 256-153, including 219-127 in 15 years as a Yankee. He also pitched three seasons with the Astros.

Pettitte, along with Rivera, Jorge Posada and Derek Jeter, was part of the “Core Four’’ of the latest Yankees dynasty. Rivera’s No. 42 is retired. Jeter’s No. 2 will eventually be retired, and there is a good chance Posada’s No. 20 will also be put away for good.

Bernie Williams’ No. 51 could also be retired.

While his 256-153 record makes Pettitte a borderline Hall of Fame candidate, there is no doubt voters will hold his admission of using PEDs against him when his name appears on the ballot.

That admission, however, did little to harm Pettitte’s standing in The Bronx, where he remains very popular with the fan base.
