12 team competitive Yahoo H2H League;

I'm currently in 7th place and 9 GB. Fought my way back from last place over the past 2 weeks.
I've been playing Theriot & Escobar over Cano & Cabrera until they come out of their annual "slow starts".
Any advice on trades or moves to remedy my weak spots? All suggestions welcome. WHIR.
Thanks!
