As I've said in response to another of your posts (I think), when Mauer tried to play at the start of '11 and clearly wasn't right, the main cause of the not-rightness was lack of strength in his left leg. The result of that not-rightness was a lot of grounders and almost always to 2B. There was also some not-rightness at the end of the prior season (leading to the surgery) and there was an increase then, too, of grounders to the right side. Now he takes a nasty foul ball off that same leg (one he described as one of the worst he's ever gotten hit with), in the same area that was the cause of problem, and he immediately is hitting a ton of grounders to 2B. Yeah, I think there's a pretty natural inclination to worry about that. I know I am. As for a couple other things you mention, yes two of the games were against Weaver and Hernandez, but the rest were not. Big time not. And for whatever reason, Mauer had previously absolutely RAKED King Felix (with a small sample as all individual matchups are, but a fair amount more than those usually have). And the infield hit to shortstop wouldn't have been an error anywhere, I don't think. It was a crispish ground ball right up the middle that the shortstop got his glove on well behind the second base bag (he was several feet into the outfield grass). A play he maybe could have made and would sometimes, but certainly not an error.
