Welcome to Sliders, a weekly in-season MLB column that focuses on both the timely and timeless elements of the game.COOPERSTOWN, N.Y. — The New York Yankees’ alumni club keeps growing in Cooperstown, N.Y.. With Carlos Beltrán and Andruw Jones heading into the Baseball Hall of Fame on Sunday, that makes 11 ex-Yankees in the last 10 inductions.The list includes folks who stayed a while, like Derek Jeter, Mike Mussina, Mariano Rivera and CC Sabathia, and others who passed through, like Beltrán, Jones, Jim Kaat, Tim Raines, Iván Rodríguez, Lee Smith and Ichiro Suzuki.You know, The Onion predicted all this.Twenty-three years ago, the satirical news outlet captured the mood of the baseball winters in that era. Under the headline “Yankees Ensure 2003 Pennant By Signing Every Player In Baseball” was a doctored photo with Mike Piazza, Randy Johnson, Sammy Sosa, Barry Bonds and Alex Rodriguez in Yankee pinstripes. The Yankees, the story explained, had signed 928 players and pushed their payroll to $5.6 billion.“We’d like to welcome the entire roster of Major League Baseball into the Yankees family,” George Steinbrenner was quoted as saying — and sometimes, it really did seem true. Johnson and Alex Rodriguez eventually played for the Yankees, as so many superstars do after making their names elsewhere.Just explore the rolls of Cooperstown. You could nearly build two full rosters of former Yankees players in the plaque gallery — 51 in all, plus Bob Lemon and Joe Torre, who managed the Yankees but did not play for them.
