In playoff semis, need some help.

[Eternalspirit]

Alright guys, I'm up 9-6 in my playoff semis, and I have some important decisions to make. Here's how scoring is:

It's a daily head to head league on Yahoo.

Me - him.
Runs, 22-21, Doubles, 10-6, Triples, 0-1, Homeruns, 5-10, RBI, 21-24, Steals, 1-2
Wins, 2-1, Complete G, 1-0, Shutouts, 1-0, Saves, 3-2, K, 41-27, ERA, 2.17-2.49, WHIP, 0.91-1.15

I need to decide which batters to play. I need to bench 4 of:

Jesus Guzman, Robinson Cano, Michael Young, Vlad Guerrero, Justin Upton, Jason Bay, Josh Willingham, Alejandro de Aza, Delmon Young, Brett Lawrie, Mark Teixeira.

I have catcher and short stop positions as well, but I have only one guy in each position, so I have no choice there.

I'm leaning towards benching de Aza, Young, Lawrie and Teixeira.

I really have no hope in catching up in HR, and probably ERA and OBP, so I need to secure my leads that I have. I'm up in every single pitching category, so I want to stack up on categories that I'm ahead in. There are only two days left this week, so this is a very important decision for me. Any help is appreciated!
