The Rockies also announced on Thursday that they have moved the starting time of Sunday's game against the Marlins to 3:05 p.m. MT, to accommodate a morning memorial service.
"Let's face it, Sunday will not be easy," Tracy said. "The game's been moved back. You think about what would Keli want. Keli wouldn't want you canceling games. Keli wouldn't want you to go out there and say, 'We didn't do too good because our mind was some place else.' No, that's not who he was. Find a way to focus in for 2 1/2 hours or two hours and 45 mintues, that's what he wanted. That's what he was all about. But I can promise you this, that's not easy, that calls on your professionalism in about as deep a manner as you can possibly imagine."
The service, which is limited to McGregor's family and friends that want to attend, will be on Sunday at Coors Field at 11 a.m. Those attending the service may enter the stadium through Gates A or D beginning at 10 a.m.
"As an organization, as a family, we continue to struggle to understand why we lost a man that meant so much to everyone who knew him," Rockies chairman and CEO Charlie Monfort said in a club press release. "It's important that Keli's family and friends have the opportunity to come together and grieve for the loss we have collectively suffered."
The club's release also read, in part:
"The Colorado Rockies and the McGregor Family are overwhelmed by the outpouring of sympathy, support and prayers in response to the tragic death of McGregor on Tuesday morning."
For Sunday's game, the parking lot will open at noon, and gates will open at 2 p.m. The pregame autograph session has been canceled.
The Rockies also plan to have a special pregame tribute to McGregor before Friday's 7:10 p.m. game against the Marlins.
Friends and fans also are asked to visit a special blog through the team's website: rockies.mlblogs.com/.
The family has asked that contributions in McGregor's name be made to: The Colorado Rockies Foundation, 2001 Blake Street, Denver, CO 80205-2000.
