Many of the players from the 1974 team will be on hand for the celebration. Hall of Famers Rollie Fingers and Reggie Jackson will make appearances, as will former American League Cy Young Award winner and AL MVP Vida Blue.

On Saturday at 6:30 pm PT, there will be a pregame on-field reunion to honor the 1974 squad. Tenace, Jackson and Fingers -- the respective MVP's for the three World Series teams -- will throw out the ceremonial first pitches. The first 15,000 fans on Saturday will receive a Catfish Hunter bobblehead.
The weekend's festivities will also include several autograph sessions with members of the 1974 team, with proceeds going to the Jim "Catfish" Hunter ALS Foundation. Four autograph sessions are scheduled for Friday beginning at 6:15 pm; the players' names will be released earlier that afternoon. On Saturday, Fingers and Jackson will hold an exclusive autograph session starting at 7:45 pm.
