something UNBELIEVABLE has just happened in my fantasy baseball league. how should i take advantage?

Okay, so today one of the players in my league, whether on an error or if he did it on purpose, dropped all of the players in his league except for Miguel Cabrera. That's right, everyone! No joke! They include:

Derek Jeter

Matt Holliday

Jorge Posada

Ryan Doumit

Jorge Cantu

Dan Uggla

Kevin Kouzmanoff

B.J. Upton

Bobby Abreu

Josh Hamilton

Vladimir Guerrero

A.J. Burnett

James Shields

Barry Zito

Scott Kazmir

Nate Robertson

Raul Ibanez

Cody Ross

Martin Prado

Russell Branyan

This means that for whatever reason, all of these players are free agents. So, I'm asking you: who should I pick up for my team? My current roster looks like this:

C- Ivan Rodriguez

1B- Justin Morneau

2B- Alberto Callaspo

3B- Mark Reynolds

SS- Jason Bartlett

2B/SS- Alex Gonzalez

1B/3B- Micheal Young
