We all kinda knew it was coming...it was all just a matter of when. Saturday, Colorado Rockies star Todd Helton announced that he would be retiring at the conclusion of the season, just two weeks after collecting his 2500th career hit. "Yes, this is it. It just seems like it's time. It's a young man's game. I am 40 years old. I am looking forward to doing something else besides baseball. Whatever that may be. I am not sure yet," Helton told the Denver Post. "I am going to start a new chapter not only in my life but our lives. It will be different. It will be difficult, but it will be exciting." Now, as you might suspect, Helton is poised to retire as, arguably, the Rockies all-time greatest hitter. But, here are ten numbers you might not have known about the first baseman’s Hall of Fame worthy career. 1950 Todd Helton's .370 career batting average against the Montreal Expos/Washington Nationals is the second best any player has had against an opponent with at least 400 plate appearances since 1950. 585 Todd Helton has 585 career doubles...more than any other active player, and 17th most ever. 103 In 2000, Todd Helton hit .372 with 103 extra-base hits.
