Reed played for Gwynn at San Diego State and in the aftermath of Gwynn's death, Reed has decided to quit smokeless tobacco. Before Saturday night's game against the San Francisco Giants, Reed threw away nine cans of smokeless tobacco, MLB.com reported.
"It's one of those things where I've done it for so long it's just become a habit, a really bad habit," Reed said. "It was something I always told myself I would quit, like next month, and the next thing you know it's been six or seven years."
Gwynn, who died Monday, had been diagnosed with cancer of a salivary gland in 2010. He blamed using smokeless tobacco for developing the cancer.
Gwynn was 54.
Reed, 25, said he has been using smokeless tobacco since he was in high school.
"It started to get bad my first year in pro ball and it's one of those things where I've always done it," Reed said. "I'd come to the field and throw one in and have multiple ones. I'd have one on the ride home, one on the way to the field and it was one of those things where I always had one with me."
Reed might turn to one of his teammates for help. Arizona outfielder Cody Ross quit chewing tobacco cold turkey in 2012.
