Todd Helton has had enough. Having decided earlier this year that this will be his final season, the Colorado Rockies star decided to go public. “I didn’t want to say I was going to return and then come back in,” Helton said before Sunday’s game against Arizona. “I talked to my wife and thought about my body and mentally how I felt going out there for every game,” Helton said before Sunday’s game against Arizona. “I’m 40. It’s time to go. It’s a young man’s game.” Helton has spent his entire 17-year major league career with the Rockies and set franchise records in nearly every offensive category. He announced his decision after Saturday night’s 9-2 loss, when he hit his 586th double. Helton began Sunday as a career .317 hitter with 367 homers, 1,397 RBIs, 1,394 runs, a .415 on-base percentage and a .539 slugging percentage.
