For his first full year in the major leagues, Hernández arrived in spring training out of shape and had his preparation for the season interrupted by shin splints. He recovered in time to begin the season in the starting rotation, where he often struggled, but occasionally showed flashes of the potential that had generated such hype. His achievements included a few more personal milestones. He threw his first career complete game on June 11, beating the Los Angeles Angels of Anaheim by a score of 6–2.
