The reality of his final at-bat in the major leagues hit Todd Helton before he stepped into the batter's box. Home plate umpire Bob Davidson handed the Colorado Rockies slugger his lineup card and Helton tucked the souvenir into the back pocket of his uniform. He struck out swinging against Kenley Jansen after singling his first time up in a 2-1 victory over the Los Angeles Dodgers on Sunday.
