Arizona Diamondbacks closer Addison Reed said he is quitting smokeless tobacco following the death of Hall of Famer Tony Gwynn.

Reed, who played for Gwynn at San Diego State, threw away seven cans of smokeless tobacco from his locker, and another two from his car, before Saturday night's game against the San Francisco Giants, according to MLB.com.

"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 Saturday. "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 played for the San Diego Padres during his 20-year career, died on Monday after battling cancer. He was 54.
