It wasn't the best of times for Robinson Cano in 2015. The Seattle Mariners' second baseman struggled during the first half of the season, hitting .238 through the end of June with only four home runs. His team, a popular preseason pick to make the playoffs, stumbled as well, with a 34-40 record. Later in the season, Cano disclosed that a stomach illness he had contracted in 2014 had left him with a bad case of acid reflux that affected his sleep and energy level. Maybe that also explained some of his baserunning lapses and defensive mistakes.
