Trade help

I am considering sending Jorge De La Rosa and Freddy Sanchez out for Ian Kennedy and Dan Uggla.

This is a head to head matchup league where pitching stats are: IP=.5 points, K=1 point, hit=-.5 poiny, ER=-1 point, W=10 points, L=-5 points.  Hitting stats:  single =1 point, double = 2 points, tripple = 3 points, RBI=1 point per RBI, HR=6.5 points for a solo shot can go up to 12 if you hit a GS. 

Right now my team is 3-1, Started off 3-0 and am losing this week as well as last week due to my pitching just killing me.  Here's my roster as stands:

C: Montero, Weiters

1B: Howard

2B:  Sanchez, Aviles

3B: Alvarez, Aviles, Sandivol (DL)

SS: Tulowitzki

OF: Carlo Gonzalez

OF: Mike Stanton

OF: Jason Heyward

Utility/DH: Alphonso Soriano

SP's: Chris Carpenter (Struggling), Matt Cain (Struggling), Yovani Gallardo (really struggling), De La Rosa, Chacin, Josh Beckett, Scott McClellan (Listed as a RP before SP so I basically get an extra starter), Matt Garza, Mike Leake.

RP's: Valverde, Leo Nunez, Jordan Walden.

What are your guys thoughts on the trade that I have on the table?  DLR is nice and is 4-0 but do you honestly think he will keep that up?  I think Kennedy is the better pitcher with higher upside.  I also think Uggla will improve his average a bit and I like his bad much more than Sanchez.  Thoughts?
