I’ve seen Latos every start in san antonio and corpus christi.  Plus fastball (consistent 92-94 with a top of 96—but the gun in sa is not to be trusted) and it’s heavy.  Breaking ball runs 10-12 miles slower than fastball. (81-83)
As pitches mount to any particular batter it becomes apparent that he needs another pitch.  Command is not good enough yet to throw the fastball on the hands consistently.  Fouls accumulate and when batter has seen and fouled more than 3 fastballs the breaking ball is obvious.  This kid with a straight change will be a top of the rotation starter.  His limitations right now will give him a little success for a crummy team.  The potential damage could be devastating.
The kid they need to get to the show is the second baseman Eric Sogard.  Compare to Robby Thompson in the field when he came up some years ago.  Hits to all fields.  LH batter and good bunter. Line drives similar to Chase Headley at this level.  Instincts and baserunning are above average.  Not much of a base stealer.  Exposure to David Eckstein from a Sept call up could only be positive.

Don’t worry folks, here you go:

I would say they are about even, as Latos getting the earlier call up may be canceled out by Latos getting shut down as Towers (SD GM) continues to state his innings are being strictly monitored.  However, we’ve all seen that these things are completely ignored when a pitcher dominates, even at a very young age (i.e. Doc Gooden, Kerry Wood, Francisco Liriano, etc.).  So I would give the advantage to Latos, as he has already been called up, and I feel there’s a better chance he dominates than Tillman dominates.
