Lock was front and center at all of Guillen's postgame press conferences in the U.S. Cellular Field Conference and Learning Center, usually testing the microphones before Guillen arrived.
"A lot of people only remember people because they play or the fans see him produce, but I think we lost one of the best guys in the White Sox organization," Guillen added. "To me, he was the hardest-working man in the White Sox organization -- and maybe in Chicago."
Lock, 52, hailed from the Kankakee area and worked for the White Sox, Bulls, Blackhawks and Bears, shooting 180 professional and collegiate sports events each year in Chicago. He was with the White Sox since 1990 and also was an award-winning producer and director of documentary videos.
But Lock's unbelievable talent was matched by his dedication and his upbeat and outgoing personality. Mark Buehrle recalled constantly joking with Lock before games and making certain gestures to keep his image off the Jumbotron. Lock would laugh, Buehrle said, and give the good-natured ribbing right back to the ace hurler.
"Some of the relievers would have fun with him and flick sunflower seeds while he was trying to shoot them," said Buehrle with a smile. "Definitely, it's a huge shock. I mean, I just saw him Wednesday morning."
Visitation for Lock will be held from 4-9 p.m. CT on Monday at Schreffler Funeral Homes, 1900 W. Court Street, in Kankakee and will continue from 10-11 a.m. Tuesday at St. John's United Church of Christ, 1045 W. River Street, also in Kankakee. A funeral service follows at 11 a.m.
Guillen and his team will be unable to attend, with the White Sox starting a nine-game road trip Monday in Baltimore. But the organization paid fitting tribute to Lock before Friday's game against the Tampa Bay Rays, with pictures of him shown on the Jumbotron and television play-by-play man Ken 'Hawk' Harrelson speaking words of praise across the stadium.
Buehrle caught Friday's pregame first pitches, including one from Chris Chelios, wearing a White Sox jersey with the name , "Andy Cam" on the back, along with the No. 1. Guillen said he will wear a specially made Andy Cam T-Shirt to every postgame interview session he does the rest of the season.
Friday's tribute ended with a standing ovation, as opposed to a moment of silence, in memory of Lock.
"He was part of the team, always talking to the players and working with the players," Guillen said. "The guy is gonna be missed. I wish the best for the family. He will always be remembered here, and we lose a great man."
"Life goes so quick," Buehrle added. "That's why I try to have much fun as I can every day out here, because you never know what's going to happen."
