The above I would keep but that is influenced by a general lack of info on my part about the remaining players, e.g Ruiz

Carlos Ruiz C
Akinori Iwamura 3B
Willy Aybar 3B
Luke Scott OF
Jose Capellan RP

It really depends on what you have at the ML level. For example, if you have Joe Mauer, Carlos Ruiz doesn't need to be kept. But if you have Rod Barajas, Ruiz would be a very good keeper.

That being said, I'd go with:
Howie Kendrick 2B
Erick Aybar SS
Akinori Iwamura 3B
Evan Longoria 3B
Chris Young OF
Elijah Dukes OF
Rich Hill SP
Mike Pelfrey SP
Chad Billingsley SP
Humberto Sanchez SP
Dustin McGowan SP
Joel Zumaya RP
Jonathan Broxton RP
Taylor Tankersley RP
Pat Neshek RP

I'd dump Willy Aybar because carrying three 3B is probably not the best use of your 15 spots. I'd really like to hold onto Callaspo if I were you, but I don't know who to drop. If you think you might need more help offensively, you can drop Neshek or McGowan. I think those pitchers are nice players but have major weaknesses when it comes to fantasy ball.
