Gum, yes, gum was an important part of the Doosan Bears winning the 2015 Korean Series
Manager Kim Tae-hyeong took over the Doosan Bears in the Korean Baseball Organization at the beginning of the 2015 season. The Bears had a strong team, but one of their issues was a young, inexperienced bullpen -- Deok-Joo Ham (20) and Hyeon-Ho Lee (23) were a couple of the relievers expected to carry some of the workload. And when you're that young, pitching at such a high level, nerves can be a problem. So, what was new manager Kim's solution?
Gum. Just chew gum.
Left-handed pitcher Jin Ya-kop admitted that the tactic worked wonders for him.
The Bears finished with a 79-56 record (winning 20 more games than the year before) and won their first Korean Series in 14 years. You know what they say ... offense wins games, gum wins championships.
