Several times this spring Piniella has had to get on his team because of their defense...
I think he is going to start the season with 12 pitchers...and that leaves 4 guys for the OF:
Soriano, Murton, Jones and Floyd.
Now DeRosa can play RF and Theriot has been playing some OF as well.
But those are the main 4 guys.
So to answer your question...
Yes he will last, and he has to because Pie did not overwhelm the Cubs and take the CF job...and I think they want him in Peoria...
So seeing as Jacque Jones has a hard enough time throwing the ball in from RF...no way he could play CF...
Floyd's legs and ankles must be held together with tape and screws...so no way Mr. Immobile can play CF. Murton is LF only.
Soriano has the speed to get to balls in CF...and a decent arm...just hope he does not slam into the Under Armour signs that will cover the green doors this season.
He is their best option at this point...he will make some errors with those Wrigley winds swirling around...but he should be able to an adequate job.
BTW...
Cubs opening day OF vs World Champs OF
LF Murton or Floyd, CF Soriano, RF Jones
LF Duncan, CF Taguchi, RF Spiezio
I will take that Cub OF.
