Trying to acquire Prado

[tommo]

Currently in a 12 Team H2H Points league with one keeper (Players eligible if drafted in 6th round or later). My team:

C: Carlos Santana
1B: Joey Votto
2B: Gordon Beckham
3B: Jose Bautista
SS: Stephen Drew
OF: Carlos Gonzalez
OF: Colby Rasmus
OF: Andrew McCutchen
U: Casey McGehee
Reserves: Erick Aybar, Eric Hosmer

SP: Jered Weaver
SP: Roy Oswalt
SP: Shaun Marcum
SP: Max Scherzer
SP: Jaime Garcia
SP: Jhoulys Chacin
SP: Jeremy Hellickson
SP: Kyle McClellan
SP: Homer Bailey
RP: Carlos Marmol

I'm trying to acquire Prado to fill my hole at second. The other owner wants Scherzer but is trying to also get someone to replace Prado. He's asking for Scherzer and Drew for Prado and another player. He was throwing around Span and Sizemore. Sizemore seemed great for the limited time he was playing, but is very injury prone. Who should I target in this deal?

His team:
C Molina, Yadier
1B Dunn, Adam
2B Prado, Martin
3B Ramirez, Aramis
SS Lowrie, Jed
OF Bay, Jason
OF Gordon, Alex
OF Granderson, Curtis
U Butler, Billy

Bench (C) Mauer, Joe
Bench (SS) Desmond, Ian
Bench (OF) Sizemore, Grady
Bench (OF) Span, Denard

SP Baker, Scott
SP Gallardo, Yovani
SP Halladay, Roy
SP Lee, Cliff
SP Lewis, Colby
RP Cordero, Francisco
Bench (SP) Buehrle, Mark
Bench (SP) Volquez, Edinson
Bench (RP) Chen, Bruce

I would have Aybar fill in at SS. Furcal and Yunel Escobar are both on the waiver wire and I was thinking of possibly trying to go after Peralta or Castro for McGehee if the deal goes through.
