Jamie Moyer, age 46 - The Phillies' southpaw could have followed my favorite storyline which features a player that wins a championship and rides the big parade float off into the sunset, but chose to return to the Phils this year. Not only is his ERA up over 5.00, but he was recently demoted to the bullpen to make room for Pedro Martinez.
Randy Johnson, age 45 - This guy has had more back problems than anyone I can remember and should have retired after his Yankee years. He likely hung on only to reach 300 wins, which he did this year. While my money is on the big surly unit retiring at the end of the year, in the last three years he's gone 23-19, a far cry from the guy that dominated baseball in the 1990s and early 2000s.
John Smoltz, age 42 - These last two years, Smoltz has only been healthy enough to start 13 games and he's gone 5-7 with a 5.96 ERA. I thought his career was over when the Yankees lit him up in the Bronx a couple weeks ago, but it looks like he thinks he's got something to offer a team in a pennant race. Good luck with that.
