PHOENIX — Todd Helton has had enough.
Having decided earlier this year that this will be his final season, the Rockies first baseman decided to go public.
"I didn't want to say I was going to return and then come back in," Helton said Sunday. "I talked to my wife and thought about my body and mentally how I felt going out there for every game. I'm 40. It's time to go. It's a young man's game."
Helton has spent his entire 17-year career with Colorado and holds franchise records in nearly every offensive category. His final game at Coors Field is slated for Sept. 25 against the Red Sox. The final game of his career figures to be Sept. 29 at the Dodgers.
"I wanted to go into the last homestand knowing it was the last," Helton said. "It was brought up to me last week that I couldn't look at it from my perspective. I had to look at it from the fans' standpoint. I couldn't be selfish about it."
Helton is the Rockies' leader in games, hits, doubles, home runs, RBIs, runs and walks.
