Dave Davison, known as "Ballhawk Dave" and whose Twitter handle is @Super_Dave, has been chasing baseballs behind the left field bleachers at the intersection of Waveland and Kenmore avenues for more than 30 years. He posed for a photo with Ross after Friday's game.
"It meant more to him so I was happy to be a part of it," Davison said. "When he hits one in the World Series, I'll keep that one."
"People don't realize when they do stuff like that, it's the memory," Ross said before Saturday's 4-1 victory over the Phillies. "I'll always remember that guy gave me that ball and was kind enough to do that. Now that guy is connected with me for life in my memory."
Pitcher Jon Lester also presented Ross with a bottle of champagne and manager Joe Maddon gave the 39-year-old catcher a bottle of wine that he autographed with the message: "If you play crazy enough, anything is possible."
"That's how I play," Ross said. "I'd never heard that saying before -- that's kind of cool."
Lester posted congrats on Twitter: "Big shout out to our elder statesman, The Grey Wolf himself, Grandpa Rossy @D_Ross3 on hitting the century mark! Love u bro! #NVQT #LetsGo." Anthony Rizzo joined in the celebrating on Twitter: "Congrats to @D_Ross3 on hitting his 100th Home Run. #grandparossy #legend."
Ross did avoid getting drenched during his postgame television interview. Outfielder Matt Szczur was ready, but realized at the last minute that he didn't have a cooler filled with Gatorade or water but one loaded with ammonia that the athletic trainers use to counter the heat.
"I grabbed the wrong cooler," Szczur said.
The Cubs did make up for that and doused Ross during their postgame celebration.
