There is growing talk about Jamie Moyer and the Hall of Fame. I think what Moyer is doing at his age is remarkable, but I'm not sure, even with his 266-and-counting wins, that he is Hall worthy. Moyer is only 65 games above .500 lifetime and his 162-game average for his career is 14-10 with a 4.22 ERA. His ERA has topped 5 seven times in his career.
Looking at ERA+ as a gauge, Moyer is at 105 for his career, which is just above average. His best mark was 132, which is not even among the top 500 seasons in history. He's had 12 seasons with an ERA+ above 100 and 12 seasons (including this year) below 100. The only categories in which he's ever been a league-leader is earned runs allowed (114 in 1987) and HRs (44 in 2004). He never won a Cy Young Award, finishing as high as fourth once and fifth once.
One the plus side, Moyer is one of only a handful of active pitchers with multiple 20-win seasons (two). From 1997-2003, he was very good, going 113-53 with a 3.75 ERA (and ERA+ of 120). If he gets Hall consideration, it's as a lifetime achievement award.
Going back to ERA+, Bert Blyleven had six seasons better than Moyer's best and 17 seasons of 107 or better. Curt Schilling had 14 seasons of 119 or better and 5 seasons of 150 or better. Jack Morris is among the most comparable to Moyer. Morris also has a career mark of 105, a career best of 133 and 11 seasons of 100 or better.
A career ERA+ of 105 puts Moyer in a tie for 475th place in history. He is tied for 32nd place among active pitchers.
