Then if you want to reduce the routine groundball beating you, why not put Matsui on and have an out at every base option? I can see your point though, so it isn't as if I think you're wrong at all. Just playing it differently than me.
That's one of the benefits of loading the bases.
If you walk Matsui, you get the good:
1. A shot at a double play to end the game.
2. A force at any base to at least get one out.
3. Minimizes the risk of the squeeze.
and the bad:
1. Nowhere to put Michaels so a walk or HBP, in addition to a fly ball ties the game, and then you've still got the bases loaded facing yet another tough lefthanded out. Forces your pitcher to be finer with his pitches.
2. Forces you to play for the infield double play on a ground ball, ie. coming home not an option.
If you pitch to Matsui, you get the good:
1. A base open, giving your pitcher more leeway in how he approaches the hitter.
2. The option of bringing the infield in to cut off the tying run.
3. A fly ball likely keeps the winning run at 2B.
and the bad:
1. Squeeze is possible to tie the game.
2. If you play the infield in, you could get beat on a ground ball that would otherwise be an out.
All in all, if I've got the tying run at 3B and the winning run at 2B, facing Matsui and Michaels, I like my chances facing those guys with a base open rather than facing Michaels and Bourn with the bases loaded. That may seem like playing for a tie rather than for the win, but I'm in a tight spot.
