Walking 6 in 6.1 innings isn't so good, even if he didn't allow a hit.  It is probably just an aberration, but you still want to make sure that it won't happen with regularity.

Also, I don't know exactly what they are working on with him either.  The extra BB may have been because he was working on something in particular.  He is working on different pitches down there, and better it happen there than in the bigs.

The relief role I can see Lincecum filling is entering the game at the beginning of either the 6th, 7th, or 8th inning in a game the Giants are trailing and then finishing that game (getting a few come from behind wins along the way).  You can reasonablely predict that this will happen at a rate suficient to allow Lincecum to pitch twice a week as Sabean indictated would be the goal if he is brought up.  This would allow Lincecum to get his feet wet with MLB hitters while the rest of the bullpen pitches with the lead and with inherited runners already on base.  If the Giants give Lincecum this role he is going to chew up 5 innings a week in two appearances a week.  The Giants will only need a 6 man bullpen and therefore will have room to add Frandsen back on to our 25 Man Roster to provide middle infield depth.

The guestion is, which 2 relievers go?  I would think that Sanchez would go down to replace Lincecum in Fresno's rotation.  Who else would go?  Not Benitez, Hennessey, or Taschner as they are pitching too well in very important roles.  Kline is signed for two years and can't be traded until June so you know he isn't going anywhere.  Do Chulk or Correia have any options left?  If not, do you trade one of them?
