"I don't know how many more there are going to be," said Helton, who brought his family along to Philadelphia and has spent the last two mornings touring the historic sites in the city. "When you see the end, it makes it a little easier to go out and give a little bit more."
When Helton debuted with the Rockies in 1997, his locker was positioned beside veteran shortstop Walt Weiss, who now manages the Rockies. Weiss said he takes time to marvel at Helton's accomplishments, even during games.
"Whenever he hits a double, hits a home run or drives a run in, he's passing one of the all-time greats," Weiss said. That speaks for itself."
Helton, a .317 career hitter who entered Tuesday batting .254 with eight home runs and 40 RBIs this season, counts being healthy enough to play at this point as an accomplishment. Last year he was already done by this time because of right hip labrum surgery. Several seasons have been affected or shortened by back injuries.
Helton spent the early part of the year sharing first base duties with Jordan Pacheco, but has started most of the games the last two months, including Tuesday, when he hit fifth and played first base.
"In some regards it is cool, most people don't play this long," Helton said. "But when you look at it, it's a young man's game.
"If I can finish the season, that's a goal. It would obviously be better winning the World Series, but it would be a small moral victory."
Helton went 0-for-4 in Tuesday's 5-3 win over the Phillies, but did make a nice play when he tagged out Jimmy Rollins to get the third out in the seventh with two men on base.
Replays showed he missed the tag, but Rollins nor interim manager Ryne Sandberg argued the call.
