It was over 10 years ago when the Cardinals made the decision to acquire Mark Mulder from the A's for a package deal of Daric Barton, Kiko Calero and young, 6'5" reliever, Danny Haren. 153 wins, 131 losses, a career 3.75 ERA and three All-Star appearances (one with the A's in 2007) later, Haren officially announced his retirement from baseball on October 22, 2015.
It barely seems like any time has passed since those days when shaggy-haired, surfer-dude-looking Danny Haren with his laughing blue eyes would tag along with Barry Zito, spending hours learning everything he could from his new mentor.
