It is a H2H 6x6 league with holds and OPS as the extra categories:

1. (6) Chase Utley 2B
2. (19) Grady Sizemore OF
3. (30) Vernon Wells OF
4. (43) Garrett Atkins 3B
5. (54) Víctor Martínez C,1B
6. (67) B.J. Ryan RP
7. (78) Carlos Guillén SS
8. (91) Scott Kazmir SP
9. (102) Torii Hunter OF
10. (115) Jason Giambi 1B
11. (126) Jason Schmidt SP
12. (139) Joel Zumaya RP
13. (150) Chris Capuano SP
14. (163) Takashi Saito RP
15. (174) A.J. Burnett SP
16. (187) Richie Sexson 1B

19. (222) Aubrey Huff 3B,OF
20. (235) Scott Olsen SP
21. (246) Juan Rincón RP

I'm thinking I may need to upgrade my starting pitching, but I am pretty happy with my offense.

Any thoughts on what I need to upgrade other than pitching and stolen bases?
