The event will highlight the Alumni Day festivities, with former D-backs players taking the field shortly after the conclusion of the D-backs game against the Giants, which begins at 5:10 p.m. MST.
The players will be introduced prior to the game with the Giants. Among the players scheduled to attend are Luis Gonzalez, Steve Finley, Matt Williams, Reggie Sanders, Tony Womack, Devon White, David Dellucci, Mike Fetters, Greg Swindell and Junior Spivey.
Players are subject to change and a more complete roster will be announced at a later time.
The D-backs held a fan vote to determine which retro jersey the team would wear that day, and the winner was the alternate purple jersey worn from 1998-2002. The jersey features the word "Arizona" across the chest.
In addition to the alumni game, the first 20,000 fans through the gates that day will receive a Matt Williams bobblehead courtesy of Chase. Williams, who played with the D-backs from 1998-2003, is the team's third-base coach.
