For the 2013 Colorado Rockies it was as close as they are going to come to a fall classic. On a brilliant Thursday afternoon turned evening with temperatures in the low 60s the Rockies beat the St. Louis Cardinals 7-6 in 15 innings. This game had more hairpin turns than Red Mountain pass. It tied for the second-longest in Coors Field history topped only by an 18-inning game Aug. 18 2006 in which the Arizona Diamondbacks beat the Rockies 2-1. At 5 hours 9 minutes it was the Rockies' longest game in terms of time this season and their fourth-longest ever. The marathon affair featured not just one act of atonement but two. Rookie center fielder Corey Dickerson who tried but failed to make a brilliant catch when the Cardinals took a lead in the eighth was ultimately the hero. He drove in DJ LeMahieu with a triple into the right-field corner in the 15th. It was the first walk-off hit of Dickerson's major-league career. LeMahieu who reached on a single looked dead to rights when he raced toward home but Cardinals catcher Yadier Molina couldn't handle the relay throw from second baseman Kolten Wong. LeMahieu who slid past the plate had to reach back and touch home for the victory. "This felt really good" said Dickerson who went 3-for-7 with two triples and two RBIs. "I was in a two-strike mode (against reliever Fernando Salas) and I got a changeup I could hit."
