Starlin Castro Called up to the Big Leagues

Starlin Castro is now a Chicago Cub. The story was first reported via twitter this morning, and now it is official. Castro is the Cubs' top prospect in the organization. The 20-year hold short stop was hitting .376 with 20 RBIs at AA-Tennessee this year. He will make the jump from double-A to the big leagues without making a pit stop in Iowa.

Ryan Theriot will shift to second base so that Castro can take over everyday duties at short. Both middle infielders were working on the field in Cincinnati today at 2:00 with coaches Alan Trammell and Ivan DeJesus.

To make room for Castro on the roster, the Cubs sent Chad Tracy to AAA-Iowa. Chad had been struggling in his pinch hitting and backup role. Jeff Baker and Mike Fontenot are effected by this move as well, because both will see less playing time.

Starlin will become the youngest Cubs short stop ever and the youngest player to make his Cubs debut since Oscar Game (19 years, 250 days) in 1969. Castro is in the starting lineup for tonight's game. Here's the rest of the starting 9:

1. Ryan Theriot, 2B
2. Kosuke, RF
3. Derrek Lee, 1B
4. Marlon Byrd, CF
5. Aramis Ramirez, 3B
6. Alfonso Soriano, LF
7. Geovany Soto, C
8. Starlin Castro, SS
9. Carlos Silva, P

The Castro callup lead to a string of roster moves in the Cubs' organization:

• Andrew Cashner promoted to AAA-Iowa.
• Josh Vitters promoted to AA-Tennessee.
• Marwin Gonzalez promoted to AA-Tennessee.
• Mike Parisi optioned to AA-Tennessee.
• Ryan Flaherty optioned to Class-A Daytona.

Our new short stop will sport jersey number 13. The last Cub to wear that "unlucky" number was Andres Blanco last season. Before that, it was last seen on Nefi Perez's back in 2006.

If nothing else, this gives Cubs' fans a reason to tune in! I'll keep you posted.
