Highest Season ERA, 10+ Wins

Here's a list of the only twenty-three players ever to win ten or more games in a season with an ERA 6.00 or higher. These guys may have won 10+ games, but no one really won when they were on the mound.

1. Colby Lewis, 2003, 10 wins, 7.30 ERA
2. Harry Staley, 1894, 12, 6.81
   
3. LaTroy Hawkins, 1999, 10, 6.62
4. Ryan Drese, 2002, 10, 6.55
5. Ray Benge, 1929, 11, 6.29
6. Wes Ferrell, 1938, 15, 6.28
7. Chris Carpenter, 2000, 10, 6.26
8. Mike Morgan, 1999, 13, 6.24
9. Pedro Astacio, 1998, 13, 6.23
10. Pat Caraway, 1931, 10, 6.22
11. Dave Burba, 2001, 10, 6.21
12. Brian Bohanon, 1999, 12, 6.20
13. Guy Bush, 1930, 15, 6.20
14. Dave Mlicki, 2001, 11, 6.17
15. Ramon Martinez, 2000, 10, 6.13
16. Red Donahue, 1897, 10, 6.13
17. Dan Daub, 1894, 10, 6.11
18. Bill Hutchison, 1894, 14, 6.06
    
19. Jason Dickson, 1998, 10, 6.05
20. Jason Marquis, 2006, 14, 6.02
21. Darren Oliver, 2001, 11, 6.02
22. Ad Gumbert, 1894, 15, 6.02
23. John Harkins, 1887, 10, 6.02

I find it interesting that 1894 had so many guys (4) on the list. The NL averaged a jaw-dropping 7.36 R/G (the highest since 1900 was 5.68 in 1930) - from 1893-1897 the league spiked in runs before dropping down to normal pre-1900 levels again.
