I apologize if this info has already been posted (because I, too, didn't want to wade through all the posts), but I heard this yesterday on teh Dan Patrick show. Roger Clemens era: 1.32 Chris Carpenter's era: 2.25 Now, when Bob Gibson set the season era record of 1.12 in 1968, the league era for that year was 2.99. The current NL era is 4.45. While the era of both pitcher's is outstanding, Clemens' era really stands out because of what the current league mark. As SouthsideRyan pointed out in the post above, if Clemens could get just a little help, he'd easily match the win total of Carpenter and then some.
