#1. It was a 2-0 pitch. In a late situation where a HR wins the game. This has nothing to do with a "bad at bat." What's the worst that could happen? He doesn't hit a HR? It's bad baseball NOT to sit on a pitch and try to pull it over the fence. #2. If Rosario walks in that situation, it's up to an obviously hurting Buxton, against a RH pitcher. If Rosario ends up walking, after never getting a pitch to hit or fouling off the ones he gets, I have no problem with that. But the Twins are NOT in a better position if Rosario walks. And that exact situation applies to Mauer ABs as well. Take a walk when it's the right thing to do? No problem. Take a walk when the next hitter(s) have a lesser chance of driving in a run? I don't think that's smart baseball. #3. Nobody is saying there's no abstract value in getting on base. I'm saying there are situations where it makes more sense to look for a pitch to hit. Don't get it? Fine. But if you do? You should be hacking, and hacking hard. #4 Mauer never takes a bad AB? C'mon. BTW, "never changing" doesn't make him a "consummate professional." It makes him someone who can't or won't adjust to the situation. Running the ball, down 10 with 2 minutes left in a football game, just because you're good at it doesn't make you a professional, either. It just means you don't understand the situation.
