TAMPA, Fla. - Monument Park soon might be in need of an expansion.

The Yankees announced yesterday that Andy Pettitte's No. 46, Bernie Williams' No. 51 and Jorge Posada's No. 20 will be retired and that the trio will be honored with plaques in Monument Park, as will Willie Randolph.

Williams played his entire 16-year major-league career with the Yankees from 1991 to 2006 and is the team's all-time postseason leader in home runs (22) and RBIs (80). According to the club, he will be honored on May 24 before the Yankees' 8:05 p.m. game against the Rangers.

Randolph, who spent 13 seasons with the Yankees from 1976-88, will see his plaque unveiled as part of the Old-Timers' Day festivities on June 20 before the 7:15 p.m. game against the Tigers.

Posada, who played in four World Series won by the Yankees during his 17 seasons from 1995 to 2011, will be recognized Aug. 22 before the 1:05 p.m. game against the Indians.

Pettitte, a five-time World Series winner with the Yankees and 219-127 in 15 total seasons with the club before he retired after the 2013 season, will be recognized Aug. 23. The time of that day's game against Cleveland has not been determined.

Derek Jeter, who retired after last season, is likely to have his day at some point in 2016.

This year's ceremonies will give the Yankees 20 retired uniform numbers (honoring 21 players and managers) and 29 total plaques in Monument Park (there also are seven monuments).

Joe Torre, Goose Gossage, Tino Martinez and Paul O'Neill received plaques in 2014.

The news about Pettitte was broken Sunday night on Twitter by one of Pettitte's three sons, Josh, and the early timing may have mildly irked the Yankees.

While the Pettitte news received mostly positive reviews, certainly among Yankees fans -- with whom he remains wildly popular -- one former teammate did not seem to share in the joy.

"Congrats to 46," Chuck Knoblauch tweeted late Sunday night. "Yankees retiring his number. Hopefully they don't retire it like his HGH testimony."

Pettitte and Knoblauch, Yankees teammates from 1998 to 2001, were mentioned in Sen. George Mitchell's 2007 report on PED use in baseball. Both eventually admitted their use of HGH to congressional investigators.

Josh Pettitte seemed to respond to Knoblauch on Monday, though it wasn't clear if that was his intent.

He tweeted: "If you know my father he's the most classy man and so deserving of this! Thanks to all the people who are supporting him and my family."
