Recent Transactions/ Projected Roster

The Tigers have invited 16 guys to Spring Training and 4 more players signed to Minor League Contract with invites.

There are a few players that could affect the major league roster.

Mantei projects to take a bullpen spot, Crabtree and  Phelps have major league experience at their positions, and Santiago is back with the team.

Are the Tigers looking to take a 11 or 12 man pitching staff into the season.  What will become of Pena.  Here is how I see things right now:

SP  - Rogers
SP  - Bonderman
SP  - Maroth
SP  - Robertson
SP  - Verlander
CL  - Jones
RP  - Rodney
RP  - Walker
RP  - German
RP  - Spurling
RP  - Percival (Mantei will fill if Percy retires)
RP  - Ledezma
C   - Rodriguez
C   - Wilson
1B  - Shelton
1B  - Pena
2B  - Polanco
SS  - Guillen
3B  - Inge
INF - Infante
OF  - Ordonez
OF  - Granderson
OF  - Monroe
OF  - Logan
DH  - Young

Big questions to me are what is going to happen with Percival?  Will Dingman or Colon show something to make a difference?  Will AAA help Grilli, Thames, and others?
